Far better than astro a40s if you ask me. I mentioned it to my physical therapist & he said said do NOT wear them. I was VERY impressed with the RGB lighting on this mouse. I was driving down the highway when the bar (which had aparently rusted through) broke in half. Or bad product in general I?ve owned several (and by ?several? I mean about 50) ;-) of these over the years and they are really hit or miss. The doefoot looks very similarly to the Alexander McQueen armadillo shoes that see wears in Bad Romance. I mounted it to the side of a laundry cabinet to avoid having to alter the placement to find a wall stud or take a risk with drywall plugs. After watching the Spike Lee film this book has long been on my reading list. 5 y pedí 8.
