iChoice Oxysmart Bluetooth Fingertip Pulse Oximeter

Selling this iChoice pulse oximeter. It's a handy little device for checking your oxygen levels and pulse rate on the go. It has a sleek black finish and is pretty easy to use, just clip it on your finger. I don't have the original box or anything, just the unit itself. Works fine as far as I can tell. Great for keeping in a gym bag or a first aid kit just in case.
