I was using this with Timo Boll ALC, with rubber on both sides. I used it about once a week for about a year, but it's still usable. After practice, I cleaned it and used a TSP adhesive protection sheet, so it still generates good spin. *I will send it with the adhesive protection sheet still attached. The size is 15.6cm long and 14.6cm wide. Evolution mxd MXD
