Calculatober Day 10: Keychain Abacus

I wrote a review for this abacus, but for some reason it didn't save so instead you'll be getting an inferior review. It shouldn't matter though because this is an inferior abacus.

Keychain Abacus
This abacus is terrible. It's the worst abacus I have ever used. The beads are so loose that the slightest movement will cause all of them to fall out of place, rendering this device unusable. This abacus is no more than a decoration for a keychain.
The picture above is the result of a slight nudge, which will be very common if you attempt to operate it.
I don't have particularly large fingers, but it's still nearly impossible for me to move a single bead at a time. My hands aren't very steady, either.

I tried to input a single number into this abacus and simply couldn't.

On the positive side, it's quite sturdy as it's built entirely of iron or steel. You're more likely to injure yourself sitting on it than bending this thing.

It sucks. I hate it. No self-respecting abacus enthusiast should own this. It's a good thing I have no respect for myself. Get a Soroban or Suanpan instead.


  1. Ok....this has to be the worst item you have ever reviewed...and I can't stop laughing.....

    1. I don't know why I expected it to be any good.
