Digit Standard Abacus Soroban Professional 17 Column (10.2 inch) Math Abacus, Math Calculating Tool with Reset Button for Adults (Brown)

Great quality!

Better than normal product, means reset button for quick operation.

This thing is so cool:) It makes me appreciate math so much more than before I started using it. It's easy to learn, and once I learned it I use it for doing math just for the sake of math. I also use it for calculations done during my studies. Its light weight and seems to be durable. I have only had it for a couple of days, so we will see how time affects it.

Inexpensive 17-column soroban with reset button. Looks nice. Good value. As expected, the buttons are small but easy to manipulate. The reset button works well. Good for learning and practicing how add, subtract, multiply and divide. I will see whether 17 columns are enough for more advanced things such as exponentiation, extracting square roots, and other operations.Learning how to use a soroban is a salubrious and very good hobby: it helps to develop concentration and mental acuity. It is not, of course, meant to replace an electronic calculator, although at some level of proficiency you could. Becoming really good at it requires a great deal of practice. But as orientals say, the abacus does not make mistakes.
