Solid and cheap replacement but interferes with other cables sometimes
I bought this a few months ago and for the most part works well. Connections seem solid and the cable looks beefy enough that it won't pull apart easily.

However, now when I plug my JBL Creature Speakers into my Powerbook while the adapter is plugged in I get a faint but noticeable low hum coming out of my speakers. Also, if I try to change the volume w/ the touch buttons on the speakers it makes a buzzing noise instead and won't adjust. I recently discovered that by keeping the power adapter cable away from my audio out cables, the problem goes away! I don't have this problem with any other power cables such as for my external monitor, hard drive, etc.

So as long as I can keep my power cable separated from my speaker cables I have nothing to complain about with this power adapter.

Great buy, Buy from mac-pro
These guys are actually a local mom and pop shop that got big with the mac boom, they are great people and although i was thinking twice about an aftermarket charger, when i saw it was them i thought for $20...The thing looks good, feels solid, and fits perfectly. I was right, these guys wouldnt sell junk. I had a junk one before but this is well worth the 27 bucks for a backup or main charger. Thumbs up.

Good and Cheap
the power-cord works just fine, no LCD light which isn't a big issue. fits just as well as Mac's original but seems a little sturdier. for its price it works great :)

replacement
Bought this to replace the original cable for my ibook... the original began fraying and breaking down after only a few months... made very cheaply.
This product, however, is very durable and I am more than pleased with my purchase.

Better than nothing?
Well, it's not the cutie lil charger that comes with the ibook, but it'll get you by for a little while, and when you have to replace it within six months you'll be glad you didn't pay $75 for the one on macstore, which lasts about the same amount of time. Honestly, when is someone going to figure out a way to make these LAST? This is my second replacement! The original died due to the flimsy little cable wearing clean through at the point where it bends away from the insertion tip, and the second just....died. Little blue light went out and that was it. Really, these things totally bite, so you might as well get the cheapest one you can, and before you spend your time on a mad search of eBay, macstore, etc. you should know there are only three or four different types out there, including the WAY too expensive original, and this really is the cheapest you'll find.
