This Abacus is actually very nice. The outside surfaces are finished in what looks like a satin varnish. The beads are either wood or a synthetic, but it is not obvious as to which material they are made of. The reset button works smoothly.

The inside surfaces of the frame are not ‘varnished’ with a aoroban overruns from the top and bottom.

abacl However this is not very noticeable and does not detract from the overall impression. Overall this item seems to be well made, sturdy, and useful. I am pleased with this purchase.

Great quality and features for the price. I did a bit of research trying to find a good quality abacus for a decent price.

We LOVE this one. It was definitely worth a few extra dollars to get the reset feature and the quality is great.

Great sroban device from Yellow Mountains Imports! Great soroban device for the price! Outstanding quality and value, this product is true to the picture. The soroban is well made sturdy with metal brackets reinforcing the corners. The finish is excellent, and all beads slide smoothly and stay in place during calculations. The rubber pads on the bottom of the wooden frame provide a very stable, level platform and keep the soroban from sliding during use. The “reset” button is a great feature to ready the device for the next calculation.

This “reset” is not present on a lot of devices on the market and was a definite plus in my buying decision. This feature saves a lot of time and effort in zeroing the device during use.

Although a little difficult to see from the picture, the frame mounting hardware and light-brown beads among the dark-brown ones help keep track of the “1” position during calculations; another definite plus that adds to the aesthetics of the device.

I would definitely buy this product again from Yellow Mountain Imports. No abaxo escapar esta oportunidad; ofrece una oferta de nuevo. Valrico, Florida, Estados Unidos.
