Different pros:
Compact, there are grooves inside for a hose, wire and nozzles, it turns off by itself, connection through a clamp, not a thread
Has some cons:
Does not show pressure when connected, but when turned on, it shows incorrectly. On my R22, the sensor showed 22022, I wanted to pump up to 2.3, but the pump shows 4.6. In the end, I decided to give up.See full review
