I have those from Cabela's. I use them maybe 6 times a year. They work fine for me, for what I do. I use them when trimming branches. I have slipped a few times when trimming walnut trees. Some of the harder woods are difficult to get good penetration into. But it has always been my fault for getting in too big of a hurry. When I take my time, I never have any problems. Good luck.
