Awesome Little Air Purifier for my Bedroom. Quit and powerful.

Fantastic assistance. Risha was friendly, helpful, and extremely quick to respond. I am so happy with the customer service chat feature!

I enter the website and was immediately contacted by your agent to inquire if they could help. I told them I needed the owners manual for my vacuum sealer. She asked for the model number and as soon as I gave it to her she sent the file. It was quick, easy and painless. Thanks so much.

Christine was very helpful! :)

After a couple of months, my personal blender went on the fritz (I simply make one small smoothie each morning). It was just bad luck I supposed so I called Customer Service. I spoke with Alex who was extremely helpful and courteous. All good, since I am still under warranty they are sending out a replacement

Fast responses and seemingly even faster replacement. Great customer service!

They got back to me quickly and efficiently.

Two parts of my juicer cracked so I came to customer support to get them replaced. I emailed and within a couple hours received a response and was assured that the two parts would be replaced. Excellent service.

I never recieved my item. I contacted customer service but they never resolved my problem. I paid for something that I never recieved. Very bad business.

I asked, and Rey delivered. He was punctual, professional and got the job done. Made his request quickly and followed up with me quickly.

Great awesome product

Excellent service the answer

Have so far 6 smaller room units and 4 big room units. My wife's allergies are much better. Thank you

This is my second purchase from Koios. I was so impressed with the quality of the first product and the customer service, that I knew I'd be back for more. I feel good that they offer me and extended warranty and a free gift every time I register. Customer service is fast and friendly and amazingly I messaged them very late at night and they immediately started messaging me. Very happy and feel great about doing business with them. I will be back for more products.

I needed to register for the warranty. Anne also provided the ebook for me! Great service!

Joy has been extremely helpful and been amazing i'm thankful for her help. Jojo-

The customer service I was provided was great, very helpful, honestly one of the friendliest and positive experiences I've had with any customer support

Great assistance. Very quick and efficient. Chat Rep John was very courteous and offered clear instructions on how I can get help.

Great customer service. Could solve issues face and we’re friendly

Had an issue with a projector I got. There were what I thought were multiple dead pixels and dust / dirt on the inside lenses. They provided me a video showing how I could try to clean the lenses and display inside the projector. The model of the projector in the video was a bit different but I was able to fix all of the spots on the display.
