You won't be sorry. Couple things. They come with sufficient instructions.

Couple suggestions:
-Buy the applicator tool.
-I have an engraving tool and use this to vibrate the valve stem as you pour the beads in.
-Don't put dynabeads into a "wet" tire. Some of us change our own and use "lubricants". Give the tire plenty of time to dry out (500 miles) before installing dynabeads. And if you used grease to install the tire, forget the dynabeads.
Your tires will always be in balance and you will notice a smooth ride at all speeds.
