This abacus is the best out of all. It is very efficient and will help your child. This is recommended.

Great value, durable and made very well.

⭐️⭐️⭐️⭐️⭐️ Excellent Abacus! Great quality — sturdy build with smooth, colorful beads that slide easily. Perfect for teaching children counting and mental math. Compact and easy to take on the go. Very happy with this purchase and highly recommend!

My opinion...I like the Abacus, it is well made except for the finish. I have the 13 bar one and I don't know why they need the 17 or 23 bar ones but maybe I am wrong, this one is just the right size for me. What I don't like is the black shiny beads, they are to shiny and they are really hard to see them unless the abacus is on a white surface as they show on their page, and if you look at the pictures that is what it is like. A brown or a black that is not as shiny would really help. The four lighter beads are not as dark as they show, they are more of an orange and are distracting and should be dark like shown in the picture. But overall I like it and will enjoy using it. Another buyer posted this but it will help you to learn the Abacus... Type in or copy and paste ABACUS: MYSTERY OF THE BEAD in the address bar. I downloaded it. Also try “Learn Clue” and “The HEV Project” on YT. Update: I returned this, not because something is wrong with it but because the black beads made it hard for me to see the beads as they were too shiny. I purchased one with white beads.

This Abacus is a beautiful product, and the Instruction Book is excellent. I worked for many years in a high technology industry, and I can tell you it's rare to see Instructions this well written. As for the Abacus itself, it's such and interesting device that with a little time and practice you can easily get hooked on it. Sure, you're always going to use your calculator, but it's fascinating to see how it was done before calculators existed. Also, the Customer Service is top of the line. Very nice people, and very responsive. I warn you though. If you have kids over 9, they're all going to want to use it, so if the adults in the family want to use it, you're going to end up needing more than one.

Well made and conforms to requirements.

Hard to dislike anything about a tool that functions this well for the money. No, it's not stained nor sealed, on the inner surfaces, that would have added a little cost. Wisely it has two rubber "feet" on the corners of one side, and one center on the other - whether they're accounting for imperfections on your surface or mfg. imperfections, who knows - but a 3 legged stool always sits flat. The instructions do differ slightly from the product, but not really annoying. e.g. The instructions note using the pins for place indicator on the rod, not between. This unit has a lighter bead for that every third rod, and the pins are instead between - so the pins are like commas/decimals; I like it that way. The reset seems unnecessary - again the the instructions differ recommending instead an index finger ran between beam and the heaven beads after tilting them all 'down' - however it works surprisingly well despite looking a bit weak. The book's method is quite simple, and rather satisfying too. Whether this will be better or worse than a 10bead frame for youth, time will tell. I do like the compact footprint of the soroban, and the extra layer of mental math (for the 5s) may pay dividends if it doesn't first add too much confusion.

Exactly as advertised. Arrived in new condition with bubble wrap to protect the product. Also, comes with a user manual. Highly recommend.
