What is your opinion of a working brake: One that locks the wheel no matter how bad you screw up your line.
How do they compare to previous pads you have used: A lot better than Moe/Spanish Fly pads.
Review: Worked great for the first few months, then started to not be so awesome. Needed tar to really work.. The little bit that holds the O-Ring in broke off on both pads, causing them to not retract at times. Pad material quickly didn't hold into the backing anymore.
If you buy them I do not recommend the Tuffak model. Also, the pad material was too thick for me to setup my brake correctly, I had to trim them down.
