I picked this up for ten bucks at FYE last Saturday (half price, woohoo!). I have to say, it seems worth it. The Amazon reviews are actually really bad, but what do you expect from a miniature camera that costs $10? My dad and I both have invisible bullseyes on our bumpers. (I was hit three times in three weeks last year plus once more on my way to work, Dad was hit twice with new cars each time, and was in one other. The year before that somebody totaled his '78 Porche and hit his SUV at 45 mph in front of a cop.) I figured this would be great to have on hand since I never remember to keep a disposable camera in my glove box in case of an accident. Now I always have something handy since I don't have a camera phone. The picture quality is surprisingly good condsidering its size- it's about the same quality as a camera phone, but a little bigger.

Cons:
Picture quality isn't perfect, but they're clear. It mostly just dulls the colors.
Pictures are deleted when you take out the battery.
Pictures aren't full size, but they're big enough.
Viewfinder takes some getting used to and isn't exact.
You have to load the software on your computer to view the pictures.
If you want to delete one pic, you can't scroll around and choose which. Only the last pic you took or all of them at once.

Pros:
Great if you don't have a camera phone.
Nice price.
Comes in grey, white, or pink, and looks cute on your keychain. People keep asking me if it's real.
Holds 20 pictures
A better (and cheaper) alternative to keeping a disposable camera in your glove box. You don't have to replace this one every six months.
The viewfinder stinks, but it STILL takes better indoor pictures than my Kodak.

There are other keychain cameras out there, so if you want one I'd recommend shopping around and checking Amazon product reviews first. Get one with a better viewfinder, or be prepared to take several pictures of the same thing so one of them turns out. The viewfinder on this one always ends up being higher than what you're actually taking a picture of.

My viewfinder sucks, but I'm fun!

Here are some pics I took with it:

Auggie at the park (he's the one behind the puggle).

Yay, there I am!

A little bit of my desk at work.

Who's that handsome pup?
