I have one too and like it!
I am into homebrew and I have a beer fridge with taps etc and the clamptite is great for the gas & beer hoses instead of using stainless screw clamps.
It is true that in some cases clearance could be a problem as you need to swing the tool sidewise to lock the wires.
But you do have an option of making a double clamp arrangement which entails swinging the tool differently so if there isn't suffcient clearance for one style of wire clamp, the other style may well be possible.
I always make sure that the sharp ends of the wire are bent down into the hose material for safety it would be pretty eary to rip your hand open on the wire end otherwise.
Neat little tool! I had to practice a bit to get proficient with it!
