Stainless Steel Mini Abacus Counting Frame Keychain

Pros: Stainless Steel Mini Abacus Counting Frame Key chain. Exactly what i wanted. I ordered this for our whole goods parts inventory specielist. We call him the bean counter. I am sure he will love this. It seems to be built well and the key loop seems sturdy. If your a bean counter or know one it is a cool gift.

Cons: It's a key chain come on. We love it. No cons on this item.

Other: Don't use this to figure your ledgers or accounting unless your books are easy enough not to get past the beads sliding back unless on a horizontal plain. There are only 10 types of people in the world: Those who understand binary, and those who don't

Pros: it's a functional abacus, provided you can use one.
solid metal form, 2 holes for keyrings, unsure of why 2.. but can't go wrong with that. nice rattle sound when shaken.

Cons: beads don't stay where you put them, must be on level, else will slide to either end. not a big deal unless you sneeze and reset it when figuring something out.

Other: solid piece, keychain sized, 1" high, 2-3" long, 1/4" thick.

Pros: nifty and cute little abacus key chain if the perfect addition to you key ring.
It actually works too, if you know how to count on a abacus this is.
solid metal construction
heavy duty key ring and chain

Cons: nothing wrong with this that I can see.

Other: good deal for the money, might pick up more of these for my friends. Buy one for yourself and all your friends too.

Pros: my smallest calculator to date!
It's cool and works for calculations, up to 10^8 - 1, which is sufficient for most cases.

Cons: Misses points on usability and ease-of-use since I don't know how to make it calculate roots. Misses some features compared to electronic calculators or paper and pen.
I used it as a decoration on my bag and the chain broke after a a while. Will probably get a new one next time I order though :)

Other: Never runs out of batteries, and it holds keys. I love this product. i bought one for me, and one for my mother who didn't know how to use an abacus.

Pros: It's an abacus! And it works, you can do some math with it if you want to. Very creative and beautiful keychain.

Cons: The corners are kind of sharp. They could have made it more rounded, as a key chain is something that often may have contact with fabric or cell phones. Also, it's too small to be used as a calculator in a comfortable way (at least for my fat fingers). Anyway, who cares? It's a keychain!

Other: Very good keychain. Just keep it away from sensitive stuff (due to sharp corners).

Pros: This is one of the most amazing devices that DX sells. Basically it is a light powdered calculator which should in theory last forever. As soon as this device revives enough light so you can see it, you can use. Really what will they think up next.

Cons: Tried to find a place to install the batteries but then I remembered I didn't need any. No other cons it works well.

Other: I even take it camping so that if I need to figure something out and don't have an pencil this comes in handy and also it just looks cool.

Pros: it attracts attention from everyone and if you know how to use a real abacus it could be even more interesting but even pretending to use it is fun. The build quality is better than I expected for such a price. It is sturdy and the pieces can move freely :-)

Cons: I cannot find any negative things about it.

Other: If you want a cool keychain or accessory to hang on your laptop case and tell people you'll use it in case of emergency (especially if you are in IT business) you can buy it :-)
