There are quite a few Chinese aftermarket power adaptors for US laptops, all cheaper, yet some are better than the originals. This is one of those. And because its used in thousands of HP desktops, laptops, and PC's, there's been plenty of time for feedback. What's the average? 5 out of 5 stars. No reports of anything bad. Some say it doesn't get as hot as the original.

The only negative point is that it has a bit of a brick look to it, and some people prefer a more elegant look.
