    The abacus is in many ways the ancestor of computers, and as an historian and computer hobbyist, I wanted a small abacus that I could discover in spare moments. This one is perfect, and I will carry it with my keys. I am not sure it would be a very useful calculator on an everyday basis, but as !... Read more

    Koşu bandının çalışması esnasında fiziksel olarak meydana gelen sürtünme ve aşınmayı minimum seviyeye indirmenize yardımcı olur. Her marka ve her model koşu bantlarında güvenle kullanabilirsiniz.

    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 :-) I cannot find any negative things it.... Read more

    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. Tried to find a place to install the batteries I... Read more

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

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

    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. 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 it...
