If you've ever seen those ads on TV talking about the latest invention to make your life better, you've probably wondered if they do what's promised. That's where NewsChannel 7's Erik Mrotek comes in with his new series, "Is It Worth It?"

The Touch N Brush is a tooth paste holder that promises you a hands-free brushing experience, But is it worth it?

Erik says his kids have been using it for about a month. The product isn't completely mess-free. The toothpaste still can gather on the dispenser and the lever, but it does come apart easily enough for cleaning.

Final verdict: Is it the kind of thing you need to have? No. But it does make it fun for the kids.

Next week, Erik will take a look at The Point and Paint.
