Query: not money well spent

This pad works great for a couple hours, and, just like everyone else, the down arrow stops registering. Don't waste your money on this pad. I am so mad that I didn't read the reviews before buying this product. Also, you can't feel with your feet whether you're stepping on an arrow or another button. And, where are the lights? Oh, and Naki's phone number and website are out of service. I'm not buying a Naki product again.
