Have these EVER worked when you really needed them too? Just because something is a low price doesn’t mean it’s a good deal either. These “inflators” are crap and I can’t recommend hard enough that people never put their faith in them.
I mean, I bought a cheap compressor, and it totally failed on me in the field, but I repaired it and put it back into service and its now 4 years running doing hard work. I paid about 3x as much but its worked for 100X as long.
PLEASE if you are going to be a compressor for your car, or if someone is asking for your recommendation...get a can of fix a flat if you are worried about the cost, or else pony up a tiny bit more for a compressor that wont suck.
