It was not as convenient as I thought. Firstly, I adjust the position according to the size, but it is difficult to use slipping to the wider side as the alignment is off when opening a little to use it.
I do not want to scratch a part, but it is best when I want to tighten it tight. While it is soft touch, it is sticky and has good striking and can be tightened with considerable strength. Although it feels somewhat expensive in price, it is useful.
