Barely holds a charge, app is not easy to use, and is inaccurate. Not much instruction on how to use it either. Cute but not very functional for its intended use.

This ring is fantastic! I originally was going to buy the Oura ring but I figured if I could save $300 and they basically do exactly what I need. I could return it if it didn’t work for me. I bought this and it’s one of the Best Buy‘s. I’ve had!

Worked for about a month & then quit recording blood pressure, blood sugar. Frustrating and very disappointing. Update. I paid the yearly fee and just after I wrote the bad review it started working again.

I have tried this thing for a few weeks, so I cannot return it, lol. BUT I figured I may as well save others money. I do not feel it is even worth the $40. It does NOT take an accurate BP, which I expected, but it's not even close. I would do the manual reading off the ring and then do the regular BP cuff. its was laughably off. It does not seem to do the blood sugar very accurately either, because I get regular blood work and the rings versus my lab work is not even close either. Ring states I am a 4.6, blood work states I am a 5.7 AIC for the 30 days that overlapped the rings measurements. BIG difference. Sleep measurements suck. I do not sleep well, so I took pics of my clock when I did my 4 or 5 times a night wake ups to compare them to the ring. The ring didn't even PICK up when I woke up well...over one week it only showed I woke up one time. I actually woke up over 31 times. So I do not recommend and would return it if I could. Hope this helps anyone else.

Received the item with much excitement hoping it would improve life. The product battery state remained unknown most of the time requiring charging often, instead 7 days touted by the manufacturer. None of the reading was accurate and consistent as we kept comparing results with standalone sensors like BP meter, Pulse Oximeter, exercise indicator etc. and everytime the product was way off. Result: the product was highly unreliable with questionable readings. So returned it with full refund - thanks for that gesture. Not recommended for purchase.

This ring was supposed to sync to the phone and the caption said no subscription was necessary, but when I went to sync it, it would not let me proceed without using a credit card. I returned it.

Does not charge.. does not hold a charge for long.. unbinds by itself and it's hard to reconnect. Do not recommend.
