I measured with a paper and ended up buying one size larger (it was 12 and with their tape it was 11), so it became a bit loose.
But the brand is very good (similar to Galaxy Watch), the brand exercises well too (volleyball). Only the steps that mark much more. The battery lasts well too (about 3, 4 days measuring the information every half hour).
Mine got scratched up a bit, but it's understandable since I'm using it everywhere, including playing volleyball on the sand.
She's perfect! I wanted to test the usefulness of a connected ring before investing €300 in a Samsung connected ring, and it's a success. It's even possible that in the end, I'll keep this one! The advantage is that it's not expensive, less than 30€, waterproof, with a screen (well in the end I think it's a gadget since I also wear a smartwatch lol). I chose the gold color and the watch is very light (feeling like plastic rather than metal). I think I should have stuck with the silver color, but I found the gold color with a very unique screen. Otherwise, the delivery was super fast!
Nice ring. As a jewelry and gadget
Excellent value. Unobtrusive monitoring of steps, sleep time, pulse and ow level.
Superfast delivery with ring cover extra 😍 , the side button is a game changer, especially reaching the proximity to check the time and functionality. App is pretty easy and quick connect.
The only downside is it gets really hot when charged.
Everything perfect. It arrived within the agreed time. The ring has quite good quality. It's ideal for getting started with this type of device.
I have a fit bit and the ring doesn't count steps like the fit bit it's a long way behind but the heart rate monitor seems to work fine.
I got it more for measuring my sleep pattern and it seems to do that just fine. It does eat the battery though but charging is easy.
Amazing product... works well .. I'm happy

I am very. Satisfied with this item and I recommend it.
Size 13 is too big for me to wear on my right foot. no problem.
All good and works pretty well. Fast delivery and good quality
Fantastic quality and fast shipping. The detail is amazing and very well made. The tiny screen seems very clean and futuristic! It reminds me of something straight out of back to the future, or running man. The price seems extremely reasonable for the quality.
I really liked the product, it arrived quickly and in perfect condition. I plan to buy more soon.
