At first I was quite scared about using it, but you soon get the feel of it.
Once you have done any heavy cutting you can pretty much us it one handed.
It's certainly a 1 handed action when you get to the final buff
You might want some tape though. Not only to protect rubbers and lights but it's also worth using to prevent polish dust from getting into panel gaps, window rubbers/felts :

I also run a length along the bottom of the doors or skirts to prevent any small bits of dirt or grit being pulled onto the paintwork from the edges or underneath.
