My daughter is in 2nd grade and this product works well for drilling basic math facts. I like that you can select different levels of difficulty and different operations to practice. I also appreciate that this is a product that will grow with my child, and she will be able to use to drill the basics for several years. And of course, these drill can be done on computers or tablets or phones, but those things have all sorts of other distractions on them; if she's working on this, at least I know it's math she's practicing!
