This is a small pliers for disposable clamps. The tool is smaller and lighter than expected, which means you'll need to use a bit more force to crimp the connectors, but that's not a bad thing and the tool seems solid enough to last a while with normal use. The tool is not very high quality. So while it looks okay, the spring is a bit flimsy and just doesn't feel very strong. It works well though and if size or weight is an issue then this is a decent clamping tool that will get the job done. I tested it with the smallest and largest clamps I had and it worked fine. It may work with other types of clamps, but I only have disposable clamps. These pliers can also be used to remove the clips, they do a good job, I usually use a flathead screwdriver to pry them out out of habit.
