I have very strong hands, I'm the person you go to to open a pickle jar... However, I found these clips very difficult to open. I was going to return them but ended up swapping them with another photographer buddy who I thought could use them better as I really can't open them effortlessly and it doesn't work in the middle of a job. If you're looking for crazy grip, this is perfect, especially if you're, say, three times my strength. If you want something with more grip this would be a 5 star rating but I couldn't use it so it's a 3.
