One alligator clip broke on first use. The metal used for these clips is so weak that it deforms and the pin that holds it together comes loose. Also, the clamps are not securely attached to the hand. You have to tighten the thumbscrew, but the metal that makes up the clamp will only warp. You can easily pull the clip out of your hand when the thumbscrew is fully tightened. The seal on the alligator clips is easily heat shrinkable. The rubber feet on the underside of the base are glued on and will loosen over time. The good thing about this product is that the metal base is very thick and the magnets are very strong. My suggestions for improvement are to unscrew the pads. on the base and improve the quality of the clips. I returned this product as I think the quality is very poor.
