    Great experience

    First time ordering from the website. Easy check out, product showed up on time and un-damage. Bought this because of the grea,t reviews on the 420 science YouTube page.

    Works!

    I just bought the larger size of this-- I have the small size as well. I wasn't sure if this was going to work but I haven't had any problems keeping my glass super clean (I'm a clean freak about my glass). It's great to buy this when you buy a new piece and use it right from the get-go. 420 Science has really great proprietary items like this and the 420 wipes. :)

    RezBlock (Put a few drops in your H20 of your pipe to keep it clean)

    This works very well. Just make sure you rinse it well anywhere your mouth is going to make contact with it because it tastes very nasty. It really keeps the grime off the glass so when it's time to clean it, it is not such a horrible mess. It makes your pipe very easy to clean. You may think it is pricey, but think of it as a gift for yourself. It's worth it!
