Magnificent design and extremely nice craftsmanship
I am very pleasantly surprised by the build quality of this inexpensive abacus. It's feels very solid and works well.I'm also very pleased with some of the design considerations that went into this model: The brass bars contrast well with the black beads making it easier to quickly read the results. having a lighter colored bead at the top of every third column makes it easier to keep track of which place value you're at. I also appreciate that the pins placed for the decimal/comma place holders are positioned between the columns, rather than in-line, just like you would write the commas/decimal between the numbers when writing the numbers out.The beads are also good sized; big enough to easily manipulate, but not so big so as to be inefficient.This may not be an ultra-fancy display piece, but it is a very functional, well built and attractive abacus to learn with.

A practical abacus built more for work than for show
This is not my first abacus, but it is the first with a reset button, and I like it.First one I ever got was a "transitional" soroban which I picked up from an antique dealer in Korea. It has one bead "topside" and five "below decks," with the former owner's name painted on the back.This one is about the same size - somewhat large, meant to stay put and not be carried around. For the true old-timers reading this, imagine the difference between a pocket calculator and an office adding machine. As I recall abacus use from my time in Korea (1990-1991), examples in this size were what you'd see at the cash drawer of the small restaurants and stores in the little village just off-post.Among the things to like about this abacus, a few things stand out:o It has rubber feet to help it stay put. Another reviewer said the arrangement of the feet makes it wobbly and perhaps it does. The obvious solution is to not lean one's hand on the thing. Proper technique discourages leaning on it anyway.o The placement of the little brass brads BETWEEN the rows of beads rather than in line with every one-in-three makes designating a "unit" column that much easier. It makes the brads appear to be where the decimal point and commas ought to be, which is visually easier to grasp.o Materials and workmanship imply practical utility over aesthetic beauty. It is built to be used.In the same way exercise makes the body stronger, use of the abacus makes the mind stronger. One of the advantages of archaic aids to calculation such as the abacus, the slide rule and the log table book, is that of instilling in the operator an intuitive sense of the relationships between the numbers he or she is working with and the things those numbers represent. In other words, one develops a sort of "sixth sense" regarding quantity, spatial relationship, magnitude, etc. by working with these old devices, which in turn makes the operator better at the math he or she is called upon to perform. Calculators and computers are more convenient, certainly, but we lose something valuable when we rely on electronic devices to do our thinking for us all the time.
