Nearly impossible to get in contact with anyone. Even my doctor's office can't reach anyone on their team for support after repeated attempts. It's been like this for almost a year and I'm just fed up with the lack of support from them to get replacement mouthpieces and a new device to replace my broken one.

Won't honor money-back guarantee. I received my eXciteOSA device in early June and commenced my therapy as directed. The device came with a money-back guarantee if the therapy did not improve my OSA. My follow-up sleep study showed no improvement, thus I reached out to Signifier in Sept to return my device and receive refund. Signifier never answers their phone nor returns any voicemail. Weeks to get any email response. Signifier finally provided me with a mailing label to return in Dec and I received the package back "rejected, return to sender." As far as I'm concerned, at this point, Signifier is running a scam.

Technically flawed. the device does not give any significant improvement. worse still the performance is erratic. the device shuts down unexpectedly in the middle of a session and cannot restart from where it left off. It fails to record so the treatment is not recorded properly. I have brought it to the attention of the company but have received no action. I have done everything they asked me to to do. All they do is send a canned reply that it has been escalated to a team. Stay away.

It worked for me, but the device quit working before the warranty was up and they never sent me a new one. They don't honor their warranty.

Three key problems: 1) the device didn’t have any affect on my snoring. Others may have a different experience. 2) the device requires a new mouthpiece at regular intervals. Despite paying a monthly direct debit, this never appeared, leaving me £200 down (plus the device itself), with a device that was basically useless. 3) trying to cancel the direct debit seems next to impossible. Six months after I cancelled the payment, the company have taken a further payment from my account, despite no DD being in place, suggesting they aren’t controlling access to my payment details correctly. Unless you’re desperate, I would avoid.

This company have taken over a hundred pounds over the last 6 months, under a subscription I set up with them to supply mouthpieces for their product. However they have not been able to supply what should now have been two mouthpieces. I've had no contact whatsoever to explain why. I contacted their support to ask them to refund me seen as they're unable to supply the goods, only to be told to cancel my subscription (which I'd already done) and that my query had been passed to their finance team. I'm not quite sure what it is that I'm querying by reasonably expecting a refund. An apology would have been appropriate for them effectively stealing my money. Seems likely that I will have to raise a dispute via my bank to get my money back. All in all, a rather shockingly bad experience.

It seemed like it was reducing my snoring a little bit, but the mouthpiece automatically deactivates after 90 days. After spending about $1000 for the device it’s annoying that you have to buy a new $150 mouthpiece every three months. If you can get one. I ordered mine a month ago, haven’t received it, and can’t even get a reply to questions about it.

I ordered a replacement mouthpiece 5/3/2024. Today is August 28th & I have yet to receive the mouthpiece. For months I've been told they expect to receive stock in 2-3 weeks. I kept my order in place when advised they would "extend" my mouthpiece. Fine, this worked a few times but now it won't connect at all. The only reason I gave 2 stars instead of 1 is because I believe the device works. Unfortunately without a functioning mouthpiece it's useless. I'm wondering if Signifier is being transparent about the reason for the backorder. I read that last June they received their largest commercial order ever, 10,000 units from a company called Spectrum Sleep Solutions. So current users are put on the backburner??? A little suspicious...

I was happy with this product until I ordered the replacement mouthpiece. After four months of waiting I contacted the company for a reimbursement, which I did receive. It’s very disappointing that I had this product for less than a year and now can’t get the mouthpiece replaced that they said I needed to replace. This was a very expensive item that I was hoping to use for the rest of my life. After reading some other reviews, I realized that I wasn’t alone in my frustrations with this company. Don’t spend your money here. This company is not reliable or honest!

According to my partner my snoring is less and softer. My sleep score on my Fitbit hasn't changed much as my snoring didn't really affect me much. I'll continue using it. What really bugs me is the control the company has over the mouthpiece. I often use it just before a midnight bedtime, so my session runs past midnight. This stops me from using it that evening. Also, if I clean the mouthpiece properly and gently there isn't any need to replace it after 90 days. It's a money spinner for the company. They are switching them off at 90 days to force sales, rather than based on actual need. I know this because I was unable to use my device for 6 weeks out of the initial 3 months and it indicated that it was about to be switched off. The company did extend it, but I think that this level of control discredits the company.

Excite OSA is an amazing company with a product that works, Using this device has been a life changer and it’s so easy to get any Question answered at any hour via the app. Highly recommend!

I have ordered a new mouthpiece over a month ago and yet still to get it We were told the mouthpiece once it had been past its 90 days would not work and not be effective and basically had to replace it at that point you cannot use it at ad it’s controlled by the manufacturer supplier so it’s in effect switched off by them And because they have stock issues they can all of a sudden extend the mouthpiece you already have Yet when asked this question before they couldn’t extend it there reason was the mouthpiece was In effective after 90 Product is good but this is completely unacceptable the reason for the mouthpiece Not a good way to treat customers

According to my sleep tracker, after over a month of use my snoring got progressively worse. I was snoring over 50% of the night. Also, my wife said that not only did the frequency increase, but the volume increased too. This is an extremely expensive device to have such lousy results.

It was working, and I was very happy with the device. However, mine is coming up for renewal, and I ordered a new mouthpiece over a month ago, and have been repeatedly told they are out of stock. Is the company still able to provide a service? I'm still awaiting an adequate response for a something I have spent a lot of money on. Customer services have been very polite, but I'll be unable to use my device in under three weeks. I was offered a time extension on my mouthpiece. I was lead to believe that it must be replaced - is this not the case, then? I understand the need to fund the product, and am happy to do that, if it is something that's works, but this just seems dishonest. In all, I've been very happy with how it works, but I'm extremely unhappy with the response I've had. I've tried to address this with customer services first; this review is just about supply issues and the length of time it has taken to receive something I have paid for. EDIT: Now four months later, and they are still unable to fulfil back orders. I recommend everyone avoid this company until they can sort their business out.

I used a CPAP machine for nearly 3 years. Extremely unhappy with it. I spoke with my sleep clinician that I would like to try Inspire device. After hearing the details I quickly lost interest. Fortunately she recommended the eXcite device. Easy to use & very effective. Finally I'm sleeping like a happy baby 👶. I wish I had known about the eXcite device 3 years ago. It would have prevented 3 years of misery with the CPAP.

The product itself functioned as promised, with its great app, clear instructions, and solid build quality ticking all the boxes. Both packaging and delivery were very good, and the customer service deserves a nod for its excellence. However, despite my diligent adherence to the instructions, the device failed to address my snoring issue. I monitored its effectiveness using a sleep tracking device and received feedback from my partner, but unfortunately, there was no major improvement. Additionally, the replacement mouthpieces are expensive. So for me overall it was not good value, and definitely not a long term solution. I have since found non-device techniques, such as adjusting my diet, modifying my sleep patterns, and incorporating mouth exercises, to be more effective in addressing my snoring issue.

I tried this machine. The shock on the lowest was unbearable. I can’t imagine the long term side effects. I am returning after one use. My tongue is really sore

I have recently tried this product and it has been a few months of use. My girlfriend says I snore less so it has been great for her. I sleep no matter what. 😂 But as an added benefit I also feel more restful once I started using the device, more oxygen in, and less snoring out….winning!! I can’t claim to understand how it all works but I’m grateful that a friend recommended this to me. The app is easy to use and the reminders are great. It will help you develop the habit of use.

My husband has been using this device for several years and it has helped tremendously. A few months ago, his charging unit quit working, so he went without his twice weekly treatments for several weeks. His snoring got worse. They sent him a new one and it i proved again. Thanks eXciteOSA!

My wife is using this for moderate obstructive sleep apnea for a little over a month now. Her snoring was super loud and kept me up at night. Now it's radically reduced to almost nothing. This is a Godsend to me. Not only is it great for her, but I'm able to sleep so much better.
