This product does an excellent job of preventing resin buildup in your smoking apparatus of choice. The only catch, is that it only works where the water touches, and you have to change your water a lot due to the build up of resin in it. So, this ends up being a  rather expensive option considering how fast you can go through it. One bottle lasts me about 2 to 3 weeks, on average, daily use. If you're as lazy as I am, go ahead and order it. You really do not have to clean your piece quite as often.
