I bought this from the other electric contractor that "I tried it a lot and Kore was the best."
It is very good as it can be adjusted before and after the suspender.
However, the flexible fastener (made of resin) on the back is weak, and when the waist bag is heavy it will break up in something.
One week has broken in a week after starting to use, and now it hangs through a binding band on the belt. I would like to make it a metal fastener.
