If you didn’t kind of see these things around for sale here and there, it would be easy to assume that this is some sort of hyper expensive medical equipment not available outside of a hospital (where they’ll bill you $800 a day for using one).
But hey, it turns out that you can get a simple and accurate read of your blood’s oxygen levels whenever you want for all of six bucks. Pretty great, eh?
These are perfect for keeping tabs on yourself if you’re ill and will also work if you’re doing some athletic training or other strenuous stuff that makes you want to check in on your levels.
Runs on regular batteries and even has a lanyard so you can keep it close without an issue.
Six bucks!
