The metal fittings at both ends were different in the picture and the one that arrived. It was good of the photo of the sliding open type metal fittings, but the thing that arrived was a type of pushing open from the outside. The spring was also very weak and it opened easily, so it could not be used because there was a risk of the hook coming off and falling.
Purchased for tool back, the fit to the shoulder is good, the pat is thick so it does not strain on the shoulder and it is the best. Because the price of the home center is around the same, it is cheap and considering continuing purchase
