Digital Standard Abacus-28.5cm-Professional 13-Column Soroban Calculator (Functional and Educational Tool) Vintage-Style Chinese Wooden Abacus.

My precious 5 year old loves this. He is not particularly gentle with it but it still looks new. Nice and smoothe

Excellent for teaching, tutoring, or just simply having fun.

This is not an abacus I would use for the rest of my life. The glossy wood finish feels overdone and rushed, rough in some parts, slightly dripping in others. The beads are a great size but very light, like the little one I found on eBay. HOWEVER. If you've only had shitty abacuses bought from here in the US, this is the best one I could find so far. Nothing like the YouTube videos I see of Chinese people owning them for their careers, though. You won't get the dense clack or stable bead position from this one. I like how the book included actually talks about a multiplication method!Amazon thinks this is a toy. It's an all-ages analog calculator.

Never having used an Abacus before, there were several features that I liked about this without having any real knowledge. The material and workmanship of this item seem to be good.The beads move very easily, almost too easy. I feel like I can make a mistake without even trying. In reading the manual, I was a bit overwhelmed by the instructions. But with some time and effort … this is supposed to be a great tool. I guess using this will help expand your mind and depend less on modern technology.I appreciate you taking the time to read this. All in all, this seems like a decent Soroban, The beads move smoothly and almost effortlessly. The product is sturdy and seems to be made well. I will keep working at it and get better at using this. Hope this information was helpful. [4 Stars]

I like everything about thisIT’s pleasant on the eyeThe construction is well done and the instruction booklet is surprisingly helpful

Missing book. Cheaply made

It is extremely well crafted and beautiful to look at even if you don’t intend to use it.

I like the abacus. The basic instruction book that is pictured in the description does not come with the abacus. One of the reasons I bought this was because it had the basic instruction book included. Disappointing.
