I ordered this set to get started as I didn't know what clamp sizes I would need. I install gas and liquid lines for beer kegs and buy screw clamps from a beer store. So far all screw clamps were leaking and were replaced by these clamps. The only thing I would change is that the tool can be smaller and still do a good job, although if you are using larger clamps than this set a larger tool might be in order. .
