Review on Pulse oximeter on a finger Fingertip Pulse Oximeter LK87 measurement of oxygen and pulse. by Anastazja Fularczyk ᠌

I took it to "* zones" for 480. It didn't start out of the box . return it? playful little hands decided to dismantle. Only latches, no glue . opening a small lid, on top of the battery compartment, showed poor soldering on the negative terminal, and the wiring simply came off when you pressed the clothespin of the device (when you put it on your finger). Soldered. Started up and even works. Judging by the fragile wiring connecting the sensors, the display and the handkerchief of this Chinese miracle will not last long.
