superb standard
I recently tried the Digital Standard Abacus, and it's been an excellent tool for improving mental math skills. The device has a simple, user-friendly design that mimics the traditional abacus while adding a digital twist for easy tracking. It's great for both beginners and those looking to enhance their calculation speed. I've noticed a boost in my ability to perform quick calculations, and it's a fun and interactive way to practice. Overall, it's a solid educational tool that I highly recommend for anyone looking to sharpen their math abilities.

Super
My son loves to count on Abacus. Everything is great. As it is written in the description.

This is a ONE star review from me, but not due to craftsmanship.
I would give it a 1 star for our personal use.... it is WAY too small.However; it is sturdy and well built... So I don't want to hurt the overall rating (which is why I gave it 5) If that's what you're looking for, it's fine. But when I say small, I mean VERY small. (my 4 year old was having a hard time separating the beads.)

Fine measurements, straightforward to apply
If you're looking for a good simple abacus, this is one worth looking at. It's well made, not too big, not too small, and easy to use.
