Great Product
I only use RezBlock on my dab rigs, so I can't attest to how well it works with resins from flower, but it sure does the trick for concentrates. I have one piece that has a cracked glass plate for a diffuser (pictured) , and it gets clogged with concentrate Fast. Like, we are talking after 4 or so dabs. I love this piece, but it was getting frustrating having to sometimea clean it multiple times a day. RezBlock helps with this, I can use the piece for multiple days now before needing to clean it. The RezBlock only works really well on the parts that the water touches, and will cause the concentrate to kind of clump up on the surface of the water, where sometimes it will stick to the wall above the point where the water bubbles up, but it still is waaay easier to clean than without RezBlock. This works wonders for those pieces that have a bunch of percs/diffusers or lots of little tubes and stuff. It will change the color of the water to a slight pink tinge, and I recommend only using about 3 drops per half cup of water, as using more can change the taste of the vapor. Not a lot, but when I do 6+ drops per half cup, it does add kind of a musty taste to the vapor. Again, I don't know how it would affect smoke, I only use it for concentrates.
