I needed snap ring pliers to disassemble and reassemble a power tool. Knipex has a solid reputation and this set of 4 covers the basics of inner/outer ring and 90Β°/straight. I only had to use them a few times. I am not a driver. I don't use them every day. I can't say anything about durability. I believe most snap-action pliers are prone to wear or breakage on the pins: they're small pieces of metal that do a lot of work. So far they have held up well and made some jobs a lot easier for me. I recommend them.
