Review on 30 PCS Alligator Clip Test Leads Set with Double-End 50cm Jumper Wire – ELEGOO: Highly Effective Alligator Clip Test Leads by Chef Deane

The jumpers work as advertised but the silicone material used for the insulating terminal covers is too slippery for the size and strength of the springs in the terminals. You will repeatedly try to squeeze the clip to open it and it will rotate sideways between your fingers in the insanely slippery shell until you finally slide the boot completely out of the clip, fasten the clip and then put the cap back on. I usually like Elegoo products, but this one. not as much.
