I am on my 3rd power cord. The first one burned out after only a couple of months. Amazon sent me another one. Only lasted 3 months and now has stopped working. This cord also gets really hot. Not sure how this got such high ratings. Wish I'd never bought it. At least it was cheap! :(

Ex Output:
Bad review

First and formost, I have owned two of these. The first one lasted 4 years, it was getting a bit fuzzy so we decided to buy another for my mother. Unfortunately after using my own wireless mouse, the unit itself suddenly started doing funny things (scrolling down, or in other words not clicking at all - as if something is missing).

Bad review
