Pros: Cheapest battery of it's kind by more than 50% in some instances. It's run the kid's car several times now and we've re-charged it and it still works just the same.

Cons: Would be nice if they sold a charger for this toy, too. Maybe it'd be cheaper as well!

Pros: Extremely comfortable for my big hands. Like the left and right buttons.

Cons: The scroll wheel was weird and it took me a long time to get used to how it worked. It's been 18 months so I forget what I had to do. BUT...the rubber started coming off the wheel and it became nearly impossible to use. So I had to return it to Microsoft - which is so far a pleasant process. I would have taken one of these in return but they don't make these anymore so I had to take a refund. Good on MS for stepping up. Too bad they don't have a comparable replacement.

Pros: Bought this for my entertainment center. Plenty of room for everything I wanted to do, easy to work with inside. It may be a tiny bit loud but it's very airy and runs 24/7. I'd rather have a bit of noise than an over-heated machine. It's never loud enough to interrupt my TV viewing. The black looks so awesome. Or rather, it doesn't look like anything and totally hides itself in my entertainment center - except for the lights (see Cons).

Cons: LEDs are insane. I taped over them right away. It's also a little deep for my particular entertainment center. I have to carefully balance it on the shelf. Not sure if my shelf is shallow or this is deep, but consider the measurements carefully.

Pros: Bought this for my Wii so I'd have room to export Rock Band 2, plus have all my DLC. It didn't work out of the box but I formatted it using Windows 7 command line format h: /fs:fat /a:4096 and it worked. I do NOT do any Homebrew or have a hacked Wii so all I can tell you is this works for DLC and regular vanilla Wii stuff.

Cons: I can't really tell a difference between this and my old 2GB Class 2 but that's just me. I'm sure if I compared side-by-side I'd notice.
