PERFECT - NO MORE EYE JITTER Rated 5 out of 5 stars

This is great!!! I use my computer for hours at a time... My eyes felt like a jumpy scroll after using a standard mouse scroll. This is a PERFECT extension. Now, reading on the PC is normal. Before the jerking when using the mouse wheel used to even get me on edge with all of my eye jerking watching the screen jerk as I read. THANKS!!!!!!!!!!!!!!!!!!!!!!!!!!!

This review is for a previous version of the add-on (2.0.3).
