Alecaremed YM504
It works okay. It’s a little slow but I guess it’s taking its time to get it right. But to tell you the truth, I haven’t found a really good one as of yet. I do wish I’d have bought one that you could read from both sides. Reasonably price, came on time.

Great but short lanyard.
The product works well. but the lanyard should be 4 inches longer.
SCustomer –
Accurate, fast, and can read it
After reading reviews, we decided on this model because my husband has recently started using a CPAP machine and we wanted to make sure what his oxygen was before he went to bed in the morning when he woke up. This does it.
