You better stick with the hair dryer when warming up the glue of the glidez.
I just performed this guide and it totally worked out. But I used a heat gun to warm up the mouse glidez. Due to the heat, the plastic that shapes the left mouse button, deformed a bit. The mouse is actually working normal, but you need a significant higher force to push the LMB now.
So be careful about the temperatures when warming the glidez.
Beside this fault of mine, the guide is perfect. Mouse wheel glitch is completely gone.
