This ring looks more like rose gold. I wanted the Gold one! Can't really give it a true rating.

Update: the seller kindly offered a solution to my problem. Unfortunately, usps delivered the new package to the wrong mailbox, but the way the ring works is good. And the seller’s communication was very prompt. This is a good company to buy from. Just size up when you order

I love this ring! The description of it was perfect! The only complaint I have is that the gold ring is more rose gold than gold color. I’m returning to get the silver color instead.

I like it but I need a size up. I wanted it for my middle finger but can’t get past the knuckle. For reference I got a size 8 but will need a 9.

The ring looks of great quality. Unfortunately even though I measure my finger it was still big so I need to replace it. Hopefully I can get the right size for the same proce.

The ring is great! Beautiful! Quality is there. It doesn't look or feel cheep. However I can only give it 3 stars because of sizing. I did the tie the string around your finger and measure it. It was not near accurate enough. And then there was a ring sizer tbst came with my ring. How is that helpful after the fact?

So I just received the ring yesterday and I like it so far. There is a issue on the app I was trying to find the watch and it lights the watch but doesn’t locate it

I like it. I wish it was flatter since it does feel a little bulky and I can’t say I love the app but it works and does as advertised. I have small fingers so it only fits on my thumb but that’s ok just something I’ll have to get used to. Overall decent product.

It’s cute. I’ve had it on for about 17 hours so far and the battery percentage is at about 62%. I charges it for probably and hour before wearing it. I wear it on both my index and middle finger.

Me encanta! 🥰 Los uso 24/7 lo uno malo es que se le cae los brillos, pero hace su trabajo y se ve genial! Para referencia yo uso talla 6 y este es talla 10 😬 por alguna razón me queda perfecto 🤩 💍

You should definitely size up. It’s a bit wide so definitely best for your pointer finger. It tracks movement well and sleep tracking seems to be accurate. The app is very user friendly. Comes with charger and silicone covers in 3 colors to protect or give it a different look. Charge every 3 days.

I love this ring. I ordered a size 9 and 10 to be sure and just choose which one fits me best. It turns out the size 9 fits me better. ❤️❤️❤️

Love how it keeps track of everything but the battery does not even last 24hrs. I charged it to 100% last night went to bed and woke up to 60% down. Now I’m get alerts about 20% or less battery life or less. I read reviews before buying they said the battery life was about 48to72 hrs that was a lie!
