High quality, great design
None, best on/off I have ever used
This CP on/off is the best on/off i've ever used. It has worked flawlessly since I bought it at cup a little over a year ago. The finish on it is great and it's constructed from quality parts. One of the things I like about its design is that unlike other on/off's that just close of airflow by closing the on/off vale, this on/off actually opens and closes the pin valve on the air tank.
If your in the market for an on/off this is the best you can get.
