This device is only good because I bought it with Play Money... Bluetooth does not work..., App Fully Chinese..., Numbers Small, But still, the Measurements he Makes Right...

Этот прибор хорош только потому, что купил я его на Игровые деньги... Bluetooth не работает..., Приложение Полностью Китайское..., Цифры Маленькие, но всётаки Измерения он Делает Правильно...

Very nice and small oximeter. You need 2 AAA bateries (not included). fast delivery to Lithuania - in 3 weeks. Works perfect.
