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

If the device is needed, I advise you to buy it because it is inexpensive and measures well Correctly set the batteries and that they are new . With its pros. A wonderful device for little money, it works no worse than an expensive one, I don’t understand why overpay? Bright screen, large color numbers. Got cons: There are no batteries in the kit, but the description said that they are not, you need to purchase it yourself, everything else is fine.
