Review: Great accessory for going Nitrox. - Great accessory for going Nitrox.
Review: Seems to work well - Ok so here's the deal: I am on o2 therapy. Wanted to actually test the large concentrators vs the tanks vs the travel ones I have decided to purchase because let's be honest even pacing through my insurance to rent theirs stiff is a scam where the sales guy is literally making a living off me renting them each month. Everyone needs a job but I don't consider myself an employer. Just my personal 411. So this handy little device seems to be pretty accurate when I measure my sats while using it. I have way more I could write but i will wait to see if anyone Actually wants me to go into detail here before I literally fill a page with useful(less to some) info and stats. So in order not to waste anyone's time,, I will be happy to update when I see a notification that this review is marked as helpful. If not, ill save my useless(full to some) info for elsewhere.

### ⭐ Price is good.......but it has to work properly if your life is on the line.
*by S***Y on July 26, 2022*

I so wanted this meter to work since it is fairly inexpensive and comes with a nice case but I think the sensor was bad and I can't trust it. I received the meter and the batteries were dead as many of the other reviews have noted. I can't believe they haven't fixed this simple flaw yet! I put 3 fresh AAA batteries in and turned it on and calibrated as directed. The reading was 21.4% before I calibrated and 21.4% after I calibrated (should be closer to 20.9%). I had a feeling there was something wrong with the meter. I contacted Forensics technical support via email and got no response after 4 days. Fortunately I took it over to a local dive shop and tried it on a tank of nitrox with a known oxygen content of 32%. Put the meter on and waited about 20-25 seconds before the read out moved. It went up to about 26% but no further. The shop worker's meter only took about 5 seconds to register ~ 32%. I sent it back and purchased a different brand before I went diving.
