very disappointing 33

1) It is very noisy, but I guess that's normal.
2) We must let it cool after 10 minutes of use because it overheated.
3) The pressure indicator is not at all suitable. graduations are up almost 20 when the tires of my car (and probably others) are between 2 and 3 ... and you only have to type on the screen of it to see the needle move, so 0.5 almost can not know the tire pressure, as saying that the product is unnecessary.

In short it can perhaps be used for something else, but for your car tires go your way.
