Badger TC910: need some feedback help

Can you elaborate on what you mean by this? “when the compressor is set to on and left alone for 20-30min the compressor dose not kick in.” Yes, if you are not using any air, the motor should not kick in. If so, it is good.

Small oilless airbrush compressor are sensitive to heat. If it gets hot during operation, it may not last too long. A well made compressor will run very quiet and very cool.
