I really wanted this to work, but I had to go back to my 1/2" rolls of tape. Unfortunately, since these things don't work well and are too steep, your laptop becomes unstable and slips on them. It doesn't really work like you think it should and that's why I'm very disappointed.I've tried swapping them out, various parts of the laptop etc but nothing has worked.The slippage became unbearable after 1 hour of use.
