    Love, love the Rez block

    It has made cleanup a snap. Most of the time I don’t even have to use a cleaning tool. I just run hot water through it and it just comes right off the sides of a bong.

    Game Changer!

    This product seriously changes the game for how easy it is to clean out your bong! I literally only have to rinse out with hot water and shake when I am ready to clean them. That's it. No alcohol or coarse salt. I will definitely be using this for life. Thank you! :)

    Rez block works

    When I first bought rez block years ago I don't think I used it right. Cause with my new water piece it's so easy to tell when I do and do not use rez block. Rez block just does what it's name says it does. It blocks resin from building up. For me it's most noticeable on the downstem. You don't have the black build up on the outside or inside of the stem where it's submerged in water. Makes cleaning that much easier, it's a bit pricey in my opinion, but if you do something well never do it for free.
