Absolutely fantastic product. These are my favorite carts to date but they do take some getting used to. These babies flow….I actually have the adjustable air hole 90 degrees from the inside intake and it works beautifully. The customer support is also 6 star as well as they handled a small problem with ny order in no time and pleasant as can be. Definitely gold standard right now.
Best carts I’ve used. I bought a couple gram carts to check out and I ended up buying ten more and two flip batteries.
Used together the variflow carts and Flip battery the puffs are unbelievably smooth.
I have been able to vape as many as four grams from a single cart by topping them off again. Since I bought a dozen, when a cartridge heater finally goes I can just screw on a new one without moving the cannabis oil and save it with no mess or bother.
Best cart on the market.
Best cartridge on the market
These cartridges are some great pieces of engineering, the variable flow rate is impeccable. One prior review mentioned that these give the cleanest, heaviest hits and that really is true. Only way to vape diamonds unless you’re using the Traveler Extreme MC dispo
Clean and smooth hits. Great product.
Best quality cartridges I’ve ever used. So incredibly clean tasting. Definitely worth it!
Won’t use nothing else,
Everything great good products
Hands down the best cartridges I’ve ever used. No leaks. No clogging. Great clouds and air flow. Not the cheapest you will find, but in this case you definitely get what you pay for (and more). Very high quality and performance. These will be my absolute go-to carts moving forward.
