I've had a bad experience with Testor's little blue compressor. The hose fitting at the compressor became so hot during use that the rubber inside the airhose degraded, expanded and "popped" off repeatedly. Once cool, I could press the hose fitiing back over the nipples and I would be okay for about 2 minutes, then POP...off would come the hose.
My main issue with this unit is with the pressure. It is not regulated and operates at 35psi. I found this to be too high. I recently purchased a Paasche D500 with regulator and moisture trap and I am very pleased.
