Product review (2 stars): Dead
I bought two of these and used them for just under two years when, one right after another, they went completely dead. They worked reasonably well during the time I had them (tho' they are a little bit loud), but consider the price for only two years of use, as I would put money on it that they will be dead inside of that time.  The company had no help to offer; the warranty was over and they couldn't care in the least that they are giving you a piece of crap.
