Negative Positive
Title: A little more than a year so far...
Review: We purchased 4 of these for our 4 laptops. They come with an on/off switch on the cord and connect directly to the lap top for power from the USB port.Out of 4, two stopped working so we sent them to our "electronics junk drawer." Going through my file cabinet, I found the warranties for them, which had expired two weeks ago. argh.So I emailed them anyway. They had me check to see if it was the unit itself or the power cord. Using a working power cord, I found the two "broken" units do work, it was just the cord.I now have an email that they are shipping the cords out to me and they should be here in a few days. Can't give them a perfect score, because after all, I spent most of the last year with them in the drawer because something was broken.My daughter says her chill mat doesn't keep hers cool enough and it is always shutting off overheating. But that could be another story.It defintely helps relieve the heat on the lap when sitting on the couch.
Is the review positive or negative?
