Lou1985 posted:I've noticed the lag/skipping with the thumb wheel when scrolling quickly (i.e. locomotive mph bounces around). It's probably because I try to spin the thumb wheel as fast as I spin the scroll wheel on a mouse. This is one case where I much prefer the speed control function on the app.
I repaired this one 3 years ago as i did not have a replacement...very smooth and still working.used this to clean and lube.
