They feel good, I was disappointed that they weren't as rubbery as the originals, but that's probably why they will last longer.

Can be a little tricky if you're too gentle, it kept sticking as I slowly worked the edges. Finally semi free and undressed (a bit scary but it worked). Then remove two screws in each section of the handle. Then the last screw under the label containing the battery/batteries. Use a tool to remove clips and swap parts.
