Well it was a reasonable price and does all I want, i.e. counts my steps, gives me my bloody pressure and heartbeats per minute. It took so long to come I had decided I’d been scammed. Strap is cheap plastic but I suppose I can always change it!


Surprisingly good features at a great price. Largely bought it for the BP/Pulse/Oxygen functions, which seem quite accurate when compared to my proprietary medical gear. Fairly intuitive to use too, with a long battery life (so far). Not perfect, but fantastic value!! ūüėä


Great ūüĎćūüŹĽ

Blood pressure dose not work... advertised as ECG dose not have ... step counter way off... would prefer one that worked
