Review on COPART Emergency Pressure Seatbelt Flashlight by Jeffery Pricinoc

The light switch was broken on arrival. Also remember that two different battery types are not included. I may have overlooked it in the product description. Let's see if a working replacement arrives. The seller requires me to return the broken one, which is also a bit of a hassle. I got the second one and it works so I upgraded it to 3 stars. No instructions were found on how to change the pressure scale, and holding down the buttons doesn't seem to do anything. I think I need to learn how to translate psi to bars. Also, the readings aren't backlit, so you can't read them in the dark.
