Jumper Pulse Oximeter Bluetooth Fingertip Blood Oxygen Saturation Monitor Include Batteries & Lanyard for Wellness Use Pulse Oximeter with Alarm

Works with freedive app and the Bluetooth connection was super easy and fast. Would recommend it to anyone who needs one

Excelente

I use it for work and compared the numbers to the one in the ER and they are exactly the same. The app is a plus.

Excelente, fácil de usar tomando en cuenta que para sincronizarlo con la aplicacion en el celular hay que encender el bluetooth y Gps.

Good service. I use this product to check my oxygen levels daily, i find it extremely accurate.

Love this product! I use it to quickly check heart rate and/or oxygen saturation. Great for asthmatics and anyone with breathing issues to monitor levels.

A very good product. Much better than expected. Highly recommended for anybody looking for a blood oxygen meter.

Good to find out heart rate quickly..seems to be accurate..
