I received my arm rest June 1st and started using it with clients June 2nd. Today is June 7th and the only issue I have is that the anti slip rubber dots move around and come off. I noticed this on Monday June 3rd after using it for barely a day because a client pointed it out. The rubber dots moved off the bottom of the legs and one was missing. I don't move the arm rest around much to clean it until the end of the day. I just wipe the top and sides in between clients. I don't understand how the rubber feet can start coming off after 24 hours. My clients love the arm rest and say it's more comfortable than a rectangle one. It's easy to clean with alcohol but should be priced lower if the anti slip feature will fall off after a couple of days.
