Yellow Mountain Imports Digit Standard Abacus 27 centimeters - Professional 17 Column Soroban Calculator (Functional and Educational Learning Tool)

My daughter enjoyed her new toy ( Abacus) 🧮 it’s to help her do math easier and it’s really sturdy and good quality

Nicely made abacus. I’ve now just got to learn how to use it

my child is happy

Arrived promptly, in decent packaging. We are pleased with this product.

Pros: Large profile making it suitable for adult hands or kids to grow into overtime. Nice price amongst the market. The soroban abacus is nice to look at. The colours of the beads help locate and memorise positions at a glance. In addition, it also has shiny brass pins on the reckoning/heavenly bar for this purpose as well. The rods are strong and allow the beads to slide nicely. The beads feel wooden and lacquered making them pleasant to touch and satisfying to hear in use. Not distractingly loud either even when using the reset button. The frame body feels sturdy, comfortable, and decently weighted. With the rubber feet as well this soroban sits firmly on a table surface without slipping much at all. Cons: The beads lacquer and paint seem to have a little damage where beads touch each other. I can only find this on one or two beads though. The frames protective varnish is rushed and flaking on the back. But what I dislike the most is how it gives the surface of the frame an odd texture on certain parts. I'd also mention the reset button, while it does work, requires the user is press it a touch harder than expected. As the bars pushing the beads in place do not completely place all the beads in a full reset position. Requiring the user to "shove" the beads using inertia. But this is not an issue after a while as you get used to pushing the button correctly. And lastly the number of rubber feet is 3. This means when resting your hand on the right side of the soroban it may have a tendency to lean forward or back depending if you rest too heavily. Feedback: This product doesn’t need much to be improved. But I’d start by finishing the surfaces better. Customers will touch it throughout the majority of its use and I believe if the texture could be better, it will be a more pleasant product. Additionally, this will help its durability. I would also like it if the colour scheme was more contrasting. A brighter brown bead against the black beads. As it is, even in a bright room, the two colours blend too well. A difference in brightness would help visually especially for seniors, children or poor sighted folk. Finally use 4 rubber feet instead of 3 to improve rigidity and stability.

Good

Ordered 2 and only recieced 1

My daughter started to learn Abacus and I searched a lot and all are seems to be expensive and flimsy. Then I bought this one with little reluctant but not disappointed at all. It’s steady and easy to use. One draw back from my daughter’s point of view it’s could be better if it have “clear the bead button like wooden one”. Thanks.

Excelente calidad y tamaño

Very useful product and easily available at amazon.

Todo muy bien

Me ha parecido muy buen producto. Es un ábaco que se nota de calidad, con peso y funciona muy bien. Es de madera y elegante. Tengo otros ábacos pero no son lo mismo. Me ha llegado muy rápido y en buenas condiciones. Lo recomiendo ya que tiene una relación calidad/precio muy buena
