Worked incredibly well for about the first 50 switch pulls or so, but then it started slipping and losing grip mid-pull occasionally. After about 100 switch pulls, it actually fell apart in my hand.
Not sure if I got a defective model or if these are just flimsy in general, but I'll be going back to a standard style puller for the time being. All things considered, this puller isn't as much of a convenience improvement as I'd expected anyways.
