I like the shape very much, but there are vehicles where the range that the handle can be turned for a long time is limited when actually using it. Moreover, it is regrettable because it is unsuitable as an on-board tool because of its length. I think that it is very easy to use if it is 3 to 4 cm shorter.
It is useful when the gap between the plug and the tank is narrow. There is an instruction to remove the tank in SM, but when you look at the air conditioning it is inefficient to remove the tank every time work is done. I also recommend it to customers.
I found out that the height was looking for a low wrench to use with a narrow car type that does not fit with a normal plug wrench. I feel that the lever looks a bit longer, but as I can loose it, I can handle it so it is advantageous if I need an initial torque. If necessary cut it and think that it should be made to the original length.
