If you're willing to trade a little style for some substance and save some money in the bargain, this is a very recommendable device. My Apple PowerBook power supply died in what is apparently typical fashion - sparking, crumbling wire where it meets the brick - and none of the Apple stores or CompUSAs in Atlanta had any in stock (which is curious in itself). I resorted to Amazon and decided to try this one out and I've been pretty happy with it. It seems sturdily constructed, and the breakaway cable is a surprisingly handy way to save on tangles. I do miss the plug-in charging light, but that's about it.

Ex Output:
Positive

Considering how much bad music is out there these days, this was nice to come across. Covers a wide range of topics and moods, musicianship is pretty good. I'd recommend it to just about anyone. My tastes are usually heavier and more progressive - Rush, Dream Theater, Iron Maiden, Queensryche. But I like this disc too.

Ex Output:
Positive

I had had two HP printers. Both broke in the same places - where the paper shoots out from the printer; the wings or the "arms" which guide the paper from the printer - both broke easily.Also I get an annoying message on my computer that the "yellow box marked !" is on and therefore I have to exit out of the printer mode and reset the yellow box so that the ! is deleted. Then go back into the printer mode. This is so annoying that I am never getting an HP Printer again.If you look on the instruction book, the annoying message can never to resolved - only by resetting the message yellow ! again, and again!!!!!!!!

Ex Output:
Negative
