Excellent install and working properly.😎

Good service very friendly and helpful

Drew from the Seattle office was awesome. Great tone, clear, did everything he could do for me and resolved my issue. Much appreciated. Great customer service.

Below 20 degrees this device will not accept a blow to analyze and it repeatedly locks the ignition until you can somehow get the handset to operating temp. There is a 'warmer' feature on the handset but it does not make a difference at that temp whatsoever. I pretty much get stranded for 10-15 minutes every time I use this device. I feel that my life would be in danger if I took out the car in the -15 expected tomorrow. Unreliable and unaccredited. Update: After leaving my Trustpilot review, an agent promptly contacted me to see if I could use some assistance. They've been quite helpful and understanding of my problems and have done everything in their power to correct them. Personally calling customer service doesn't work. Both times I've tried, I waited 75 minutes and was hung up on after talking for 15 seconds. Thanks Trustpilot for holding these companies accountable, someone needs to.

I am currently on hold with customer service and have been for 75 minutes and counting. I have had my intrerlock device for 9 months. The first few months it took me some time to get used to, but no major issues. As soon as the weather started to get cold (I live in Pennsylvania, and it can get quite chilly here), I started having major device malfunctions. I am currently on my 3rd device in 6 weeks because of device malfunctions. Here's the best part - they're never even the same issues! I've had a device with issues that strange codes pop up and then a substantial number of days are magically gone, a device where there are strange noises coming from the steering column and then days are magically subtracted, a device where I would get a "FAIL" message before I had even blown into it, and this device that I'm currently on hold regarding just gives random messages every time I blow into it and also transmitted the message that I was disconnecting my handset. This one really upset me because I don't even know how the handset disconnects and I resolved myself to just biting the bullet and getting through my interlock period as painlessly as possible. Just a few hours ago, I left my house, blew into the device to start my car, got a "PASS" message no problem. I go to the ATM down the road from my home, leave the ATM, the device asks for a rolling reset blow. I blow into the device well within the timeframe allowed, and almost immediately get a "FAIL" message. I roll my eyes because I am just so tired of the device issues. I pull over to the side of a busy expressway, turn the device off, and get a "WARN" message. Note: nothing had been near my mouth or the device since this journey started less than ten minutes ago and prior to leaving my house there was no food, beverages, toothpaste, mouthwash, or anything else that could have caused any issues. Three minutes after I had started the device again, it asks for another rolling reset blow. I once again blow into the device, and instantly get a "PASS" message. Note: these events all happened within the course of 15 minutes or less. So the readings that this device transmitted was that in a 15 minute period, I was sober, drunk, then blew trace amounts of alcohol, then was sober again. The experience and the way that this company does business is deplorable and I'm not sure how they're still permitted as a vendor. The only good thing about this experience is that the boys at the service center that I use are excellent and understanding. If you ever need to contact customer service - brace yourself. You will be on hold for several hours, and they are rarely able to provide any assistance whatsoever. Even though I am 75% through my interlock period, I have begun looking at other vendors because I am not going to let this company's faulty devices add time to the period that PENNDOT has designated, which is exactly what will happen if Guardian Interlock devices continue to constantly use faulty equipment which transmits incorrect information to the DMV. I have been asked a few times who my vendor is, and I have told every single one of these people that I don't know anything about other vendors, but they have to be better than these people.

Ive had my device for a couple months and when I originally got it installed.. the sample required me to blow, blow/hum, and inhale... well they recently changed it and know its just a blow hum and i'm having so many problems with it. Every time I give a sample it says my blow and hum is too loud and I keep trying to fix my blow and hum to what its asking of me and it still doesn't work. I just got off of work and I had a rolling retest and I kept blowing into it and it wouldn't take my samples because it kept saying the same thing and I kept trying to change my blow/hum to what it was saying, but then time ran out and it came back as a refusal. Im aggravated and i'm not sure what i'm supposed to do. I don't drink alcohol anymore and I don't want to be in trouble for this. The blow, blow/hum, and inhale was so much easier and i'm angry that I now have a refusal on my record after I repeatedly was doing what I was told to give it a good sample and it wouldn't work.

DO NOT USE INTERLOCK. The machine malfunctioned, and was stuck on a " blow" on the display afters retest. Worried about it, I called interlock, in which no one answered. When I got home, I cut the car off and the words still displayed. It took me over a hour, and multiply holds, to finally to talk to someone from interlock. Interlock told me that I am locked out due to a violation, even though I explained I did everything correctly. She noted that there must have been a count down, displayed. The thing with the device is, there is always a count down after you initial retest.

I was lied to today by Guardian Sydney staff member. This has made me quite annoyed and is very unprofessional on her part. It also doesn't align with the company's value of 'integrity'.

I have had trouble with my Interlock since day one. I received a lockout code on Thursday it was accepted but when I went to start it it was locked again. I have been calling since with no luck. A few times I did get a hold of some one the put me on hold and never answer the phone again. A couple times that I was on hold it was for a hour then they ask for you to leave a message. When someone finally gets a hold of me it's after 5pm and my shop closes at 4 and it's an hour away. Worse customer service I have ever dealt with.

This company is the worst. Device continuously resets days that are paid for and they will not give credit for those days. You have to pay for another device and more days. Anything can make this device give a negative reading. Toothpaste, mouthwash, perfume, air freshener. I KNOW it's the device because I pay for it for my sister and when it malfunctions I have to go take her where she needs to go. And having known her for 55 yrs, I know she hasn't been drinking. Even if she was it should just not start the car, not steal all the days that were paid for. Unfair company. Keep money that doesn't belong to them.

Awful... Equipment is faulty always messing up. I call every time it goes into relay mode guardian advises to do a hard reset, then chargea me 60 bucks to have a reset done cause the hard reset throws the IID into a violation, due to their faulty equipment but i get charged for it. I can't get the equipment switched out, there are no installation shops closer than 2 hours and 45 mins away. I should NOT have to pay or be put in violation because Guardian Interlock IID is crap and doesn't work half the time.

HORRIBLE. Every time I come in for a calibration. I end up spending 2 hours hear because their equipment is faulty and they have to reinstall a whole new system.

I WAS IN NEED OF SWAPPING MY INTERLOCK FROM ONE VEHICLE TO ANOTHER, I WAS NOT GETTING THE SAME INFORMATION FROM ANYONE I TALKED TO. THAT IS UNTIL I GOT MARIA GONZALEZ AT THE GUARDIAN PA STATE OFFICE. SHE KNEW EXACTLY WHAT NEEDED TO BE DONE, AND SINCE MY VENDOR HAD BEEN GIVING ME A HARD TIME ALL WEEK, SHE WAS ABLE TO SCHEDULE ME AT A DIFFERENT VENDOR FIR THE DAY I NEEDED MY APPOINMENT TO BE SCHEDULED. MARIA TOOK OWNERSHIP OF MY ISSUE AND MADE SURE IT WAS RESOLVED. GUARDIAN IS LUCKY TO HAVE AN EMPLOYEE LIKE MARIA

This is company is absolute garbage. I cannot even express the issues that have plagued me regarding this device and customer service. The machine has been faulty on multiple occasions and was poorly installed (wires hanging on the brake and gas pedal). It has drained a brand new battery twice. The customer service is absolutely useless. I've had my driver's license cancelled because they didn't send in the paperwork. They've also charged me 3 extra times which is illegal. I have contacted my attorney and will do everything in power to make this right.

August 2, 2013 Initial Rating 3 *** Sold my car after one month of installing the interlock device and so had to reinstall on the new car. All of a sudden, the introduction price of $68/month for a new customer is no longer available but got locked into a higher regular rate at $80/month. Called customer service after realizing what happened. Didn't notice what I was paying since covered by financial aid for a few month. Rep says its my fault for not paying attention. Not going to do anything. Rip off!!! Updated Rating August 3, 2018 5***** I was contacted by Maggie Moore, the Client Service Supervisor and she able to resolve my issue. I was very appreciative that Maggie took her time to investigate my account and able to correct my monthly payment to the original installation date. I am very pleased with this new outcome and will contact Maggie directly if encounters any future problems with the call center customer service.

I have had to bring in my unit 3 times in the past month for resets. When I go to start my vehicle is will tell me I fail. I wait 5-10 minutes and then I pass. I have a portable breathalyzer because of this very situation. It always reads 0.000 when I try directly after it fails me. One morning i started the vehicle fine. 10 minutes later I fail the rolling retest, then 1 minute later i pass the retest. This does not make any sense. The unit has been replaced 3 times because it was faulty. I have tried to call and message guardian to no avail. This is completely unacceptable and this all started because they decided to upgrade their unit and it doesn't work. Luckily I have all these things on video as I tape myself every time I get in the vehicle now.

At this point, I feel it would be in my best interest to cancel with this company. I just had the device reset on Wednesday 7/25/2018 and I am having to take it again to have it reset. How is it possible that I can start my car..no problem...but get a rolling and I cant pass. I have had this device just 32 days and every week I have to take it in for a reset. I don't have that kind of money or that kind of time. This should be easy not difficult. I am beyond myself with anxiety. I just want to be able to blow and go!

All I can say is when Andrew picked up the phone it was probably the best conversation with somebody you didn't know you could have. Felt like I was talking to a friend not being treated like a regular customer. Give that guy a raise asap.

Where do I start. To begin, the device costs an arm and a leg, but that’s beside the point. I have had the device for a little over 3 months now, and it has permanently locked itself out twice, which requires me to pay an additional $50 to get a code to unlock it for 2 hours. When it is working, the device takes an average of 40 seconds to “warm up”, and that’s only in warm weather. God forbid you ever have to call customer service, because you will be put on hold for 30+ minutes. I’m currently on hold as I’m typing this, and I have been for 51 minutes and counting. Both times that I had to pay $50, it was a malfunction, and they said they would look into me getting a refund, but as you can guess, that never happened. I have only had 1-2 customer service representatives that have acted like they remotely have a clue about what is going on. Usually I get transferred 2-3 times per call, along with the hold time. This has to be the worst company in the United States. Do not give them your business. If it wasn’t such a hassle, I would have already switched companies. But if I did that, it would be another fee to take the equipment out of my truck, along with the new fee of the other company.

Equipment is teriable. They seem to setup equipment so you have to go in and reset which cost money. Stay away from this company at all costs .
