What Our Customers Say
Sarah Thompson
Very good Prodo, it works perfectly. I still do not know the accuracy of the data collected, I will only know after a few weeks of use. The item came sealed in the box and well packed.
Emily Rodriguez
The package arrived before the expected date. The item itself works and feels great. The application works perfectly with IOS. The product is great and I recommend it. It measures everything from sleep and heart rate to physical activity.
Jessica Patel
The ring is amazing for this price. I usually don't wear rings and watches because I don't like the feeling. I have a smart watch and I bought the ring to try to see if it will be more comfortable. The application is quite simple, but it follows everything it says in the description. I wore the ring last night and it monitored my sleep perfectly, it monitors light and deep sleep. I recommend this ring because the functionality it offers is great
Olivia Lewis
The ring arrived fine and so far everything is working well. Primarily it was bought just to test whether I would use something like this. I have a smartwatch, but I don't wear it to sleep, so this is an interesting addition to my sleep tracking. Size eight is good, I have thin fingers and the ring fits both middle and index finger. The first stress test is done, now I just have to figure out which hand and finger I'm going to wear it on.
