Clean Trash. I used them for a total of 15 minutes and they broke. Small clips break very quickly with very little pressure on them. Luckily I have a neighbor who can weld it back on and have those clips fully functional again. Now I can really pinch and hold things. I have 2 of these and purposely broke all 4 clips to weld them on. Looks ugly but works great now. Thanks Irwin for selling me cheap junk.
