Query: Terrible tool--stay clear!

Snap ring pliers with interchangeable tips have been around for a long time, so this versatile set (four tips in total: straight and bent tips in large and small diameters, that can be placed in position for either internal or external snap rings) looked very attractive. This tool was a complete disappointment, however. When installed, the tips wobble, then fall off when sideways pressure is applied. There is a removable pivot with a cross-bar that is supposed to lock the tips into place when using the external position. Instead when you put the tips on, "lock" them into position and turn the tool over, everything (tips and lock) falls off the pliers. I did a double take! As you know if you've used snap rings, you must often work in a difficult orientation and apply some downward pressure to keep the tips engaged in the small holes in the ring. A rigid tool that you can trust is absolutely necessary. This tool is unusable and should not be on the market. For shame, Irwin!
