I've had several different kinds of retaining ring pliers and they've run the gamut from cheap and fragile (harbor freight) to sturdy but worthless (the craftsman variety that uses a screwdriver handle to turn an expanding mechanism). I've managed to snap the tips off of a lot of them.
So my wife wanted Christmas recommendations and this is about the only tool I really need.
What products have you found to be very usable, and durable?
