I've been using these levers for years, and have never had a problem with 'em. I've tried the other ones out there, and aside from a high dollar set of titanium levers, these are the best I've found.
They have a hook on one end, to latch the lever to a spoke, which is real helpful with today's tight fitting clinchers. The spoon edge is also small enough to get under the bead, without much hassle.
Removed old and installed new tires (first time doing the process myself). Things went pretty smoothly. The size and weight of these feel good in hand, the hook to clip onto a spoke is very helpful, and the slickness eased the installation process.
