Excellent customer service I have delayed sleep phase syndrome and am using my glasses to move my schedule up with my sleep doctor’s advice. AYO quickly replaced my new pair of glasses when I had some issues. They are very responsive to my questions with how to use the app and the emails about sleep are very useful.

Excellent customer service Very responsive and positive outcome from contacting customer service. Their delivery algorythm routed my order thought the UK for a deliver to Ireland so I ended up with a €70 bill for customs charges. Within five minutes of contacting them they apologised and paid the bill themselves and I received the order a couple of days later. It's too early to review the Ayo product as only using it a few days.

First off AYO has amazing customer… First off AYO has amazing customer service. They really helped me get set up with my App. 2nd the product has really worked for me with normalizing my energy and sleep patterns especially with less sun during this winter hours.

I am now on my 3rd pair of glasses I am now on my 3rd pair of glasses from AYO. It's been a great experience in general (mostly just issues with the app) and the glasses really help when the days get shorter. Every time I have had to reach out to their support team I get a response within 24 hours and from someone who knows what they are talking about. I always get my issues resolved and quickly.

Best customer service Best customer service The service received from AYO was exceptional. I purchased my replacement AYO as after 8 years I managed to break the old mini usb loading plug and I had an upcoming trip. All effort (including extra shipping cost paid by AYO) was made to ensure I received my device with time to prepare and I received personalized tracking information making sured it arrived in time!
