What more can I say than that they work great? They fit my M705 perfectly, and swapping them out was pretty simple. I just grabbed a flathead screwdriver and pried the old ones out. It's important to note, though, that the little squishy-feeling adhesive beneath each of the original pads should be there. It's actually used to hide a couple of screws under the large pad. I think my only complaint with these is that the edges are sharp corners instead of rounded, so they tend to catch on the side of my mousepad if I swing my mouse a little too far. But at the same time, they're thick enough that I'm sure they'll last quite a while.Anyway, I've had these on for a week or so now and they've made my two-and-a-half year old mouse feel brand new. Sure, a new M705 is only $33 nowadays, but I'd say these are absolutely worth the $8 I paid for them. Considering you get two sets of these, if you use them on one mouse, the buttons on the mouse itself will wear out before you run out of pads.
