Yes. But not a yes, if it’s a matter of life or death. Let me explain.

It is a GREAT idea and does work. I do prefer taking my fat rips (not really fat), with one of their mouthpieces. It does cut down on some of the smoke burn, I like to call it. However, I can live without it, for the moment. Ask me again in a few weeks?
One thing that is true about them, is that you can easily see all the gunk it catches. Which is dope, and makes me feel like it is helping a lot more than I realize.
I have been using their mouthpieces on and off for a couple of years. It fits in the majority of pieces and seems to age well. Mine just now, is starting to show its age. (3-4 years old)
The second thing, is they have super fast shipping from their website. I’m in BC, Canada and my order got here within a week… with no damage. A lot of our shops here don’t carry their products, or have refills available to purchase – only packs. So while I was restocking my mouthpiece filters online from them, I ordered something called a mini mouthpiece for joints or vapes? TAKE MY MONEY. So far, they don’t fit well on my Canadian vape batteries / dispo’s but I’m not giving up on it yet.
Thanks for reading. Have you tried this product out before? Spark up in the comments for me!
