    Love it!

    7 drops in a 21 inch tobacco master Presidential will keep it clean for a long time....I usually change my water every day even if I dont use Rez Block but still get a resin ring in the pipe however with Rez Block the ring that usually develops is simply gone....the question I ask is if the Rez Block makes the water retain the resin, would this also keep resin out of our lungs, a potential added bonus...? I know my pipe is much cleaner and easier to clean and I could add more Rez Block for potentially a more positive effect, but I have not tried it. The Rez Block did not appear to effect the taste of the hit but seemed to have made the hit more smooth.

    Amazing!

    Ummm, this stuff is AMAZING. Makes cleaning my pieces a breeze, all I have to do now is empty them and then swish some water in there and then it's clean! Oh and it also is a red liquid so it makes your water look cool!

    Must Have For Any Glass Water Pipe

    In the last 3 yrs I've purchased #2 of the smaller 15ml bottles and recently #1 of the XL 30ml bottles. Typ this stuff will last a few months changing out your water weekly. This stuff really works and one time I let my 12" beaker go for about 4months and even after all that just a quick wash with warm water and about 30 secs of Formula 420 cleaner and it was like new. If you change your water every week or sooner then all you should have to do is run hot water through it and your done. This stuff basically coats the glass inside the pipe making it so the Rez won't stick to the sides of the pipe and all the tar & Rez are basically stuck in the water. This stuff is alittle bit expensive IMO, but it's worth it to a serious smoker and it will last a while. I recommend this to all my friends and family that may need something like this to aid in their glass cleaning. I will add that new RezBlock water does change the taste a tiny bit the first day or a couple bowls. Also sometimes this stuff lasts forever without growing any slime and other times within a week it has stuff floating around. Typically if I fill up 12oz of water I put in 14-18 drops and that seems to be the sweet spot for my needs.
