I am impressed with their quality at this price. They are strong and the edges are very smooth and will not pierce the tube. It's nice to have a tool to help with tire removal. Oh, and there are 3 of these things, not 2, that's even better!
Pros
These buckets are great for slow speed bead work and getting a firm grip on the tire edge. They don't have an aggressive flex, so they slip easily between the tire and rim bead. And rim protectors are used to protect rims from scratches.
