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.

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!

I just got my unit and have tried them… I just got my unit and have tried them twice today. Nice blue light, I am waiting to feel better, only have used them twice in a single day. The data says it may take 14 days to get full benefit so I cannot comment yet.

Exceptional service and support The service received from AYO was exceptional. I purchased my AYO as a friend had told me it would help with jet lag 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. I also received personalised recommendations tailored to my itinerary.

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.
