Customer Ratings:

I've used the standard rectangular flash cards and never liked them--all those cards to mess with, and they always seem so disorganized (maybe it's just me!). I am delighted to report that these cards are fantastic--easy to use, easy to store, fun for my kids, and ORGANIZED! By that, I mean that (for example) the +2 card has all the -2 facts on the back, and the answers to the front are clearly visible on the back. The round dial works smoothly and is durable with proper adult supervision, making these by far my flash cards of choice! I also bought the multiplication/division set and have been equally pleased with those. Thanks, Trend, for thinking outside the "box" and offering a more "rounded" approach to flash cards!

The idea of math practice with the wheel is good. The portability is good because you can take a few wheels with you in case there is something specific to practice. As far as durabilty it is thin cardboard so it all depends on how much care you take. I think the price is expensive for what it is. I paid almost thirteen dollars and yes even though it is a wheel it still serves more or less the same as flashcards which are 1/4 the price. I wouldn't recommend this product simply for the price factor. For that price you can buy some cubes and rods and teach hands on math.
