Review on Portable Frequency Cutting Voltage Inverter by James Duffield

Updating my review, I didn't realize I would need a regulator to get my shop air pressure down to 75psi, after getting the air regulator and hooking up the unit, it works fine. I only gave 4 stars because I didn't know the air pressure. Also, the fitting on the back does not have a 1/4 pipe thread like most air lines. Therefore, you must use the hose that comes with the machine. The bottom can be longer and the cutting hose a little shorter. Overall a good deal!
