Works great. Having batteries included was a plus.

Portable pulse and oxygen saturation meter. For the price, everyone should own one. We use this daily to check heart rate since our doctor wants our heart rate below 100bpm. The device is quick to read, clear, and easy to use.

A pinch sensitive to positioning on your finger. Use your middle finger and get it in as deep as it can go (comfortably) - on any of these sensors. Sure, you can use any finger, but the larger the skin surface and blood flow, the more accurate the measurement. The laser is basically looking at the color of your blood - through - your skin. So wash your hands (engine oil, sun screen, etc will degrade the reading) and watch out for callouses. The sensor doesn't care about the color of your skin. It cares that it can bounce light off the capillaries I didn't try the the blue tooth feature or download the software, but I did get a reading in my blutooth list that it had found it. It can only be registered for use if the software is installed. My phone would not connect to it because I did not download the software.

Very handy to be able to monitor heart rate and oxygen daily. Clips on finger easily and one click does it. Pulse rate and oxygen level show clearly. The fact that it comes with it's own batteries make it easy to use right out of the box. Worth the 5 star rating.

I bought this to follow my oxygen levels while I was sleeping. First off, the instructions are just barely adequate. I downloaded the app onto my google phone (it doesnt work with my amazon/kindle fire reader), updated the software, and good to go.A couple of negatives here; while it saves the info in a graphical form, the data cant be sent or opened as a spreadsheet for manipulation. There is a specific order to how to turn off the oxygen meter or it wont save the data you just recorded. It eats AAA batteries, goes thru a set a night but the battery indicator will let you know in advance. The meter O2 number rapidly flashes sometimes, figured out this is due to the O2 number being below their preset alert number (I think it is 88%?) but no mention of this in the manual or after contacting their customer service (they asked me to send a vid of the "problem"). Overall, i give the meter a 4, good value for the money; and the instructions, manual etc. I give a 2.

The oximeter is probably the equivalent of similar devices at 2X the price. Upon going to the Wellue website I found only more expensive measurement and diagnostic tools ($50 to $250) and not this entry-level product (FS20F), which is probably what sellers refer to as a "loss leader." Although the FS20F synched up through Bluetooth, it appears that any coherent tracking of a user's history requires subscription to Welllue's tracking and cloud services. I think I'll remember my O and P levels with my own occasional, unrecorded readings of the device.As for the device, it seems accurate and is easy enough to use. Just several clarifications: 1. You will need to put the oximeter on a finger of the right hand and not the left, unless you plan to read the screen upside-down. 2. You need to press the button to "activate" the device for finger insertion. However, you do not need to re-press the button upon removing your finger as the device will de-activate automatically. 3. Upon de-activation, the power remains on and the batteries will eventually discharge. To preserve battery life (2 AAA's) simply remove them (the instructions suggest after 30 days). 4. Be patient with inserting the lanyard. (I had success after wetting and winding the loop, which I then inserted in the hole facing me before pulling it out from the hole on top.)Finally, don't panic if your reading of the oximeter is closer to 90 than to the recommended 95-100. The guidelines for reading the number, I'm convinced, are overly insistent re the top number; overly alarmist re the bottom.
