Customer Reviews
Everything is perfect and shipped very quickly
Works very well for a first ring and for the price. Application to be improved. Battery lasts a maximum of 2 days, not 5, as advertised, even with basic adjustments.
Product ok but, below the competitors. Bad delivery.
I received the ring within the announced timeframe, thank you. However, the documentation is incomplete, we don't know what the numbers displayed in the ring correspond to: the time and what else exactly?
Very bad. Lasts less than 24 hours with minimum functions. I asked for a return and refund and they didn't approve me. Thieves!
