When I first started making carts, I of course went for the cheapest ones.. I was paying 49.99 for a box of 100. I soon realized that putting good oil into garbage hardware wasn't logical, and have been trying different brands, comparing bang for your buck and just overall quality. These might cost a hefty $220, but really, that's $2.20 each, compared to, what, $1.39 for the ceramic cores? And, EVERYTHING about this cart meets or exceeds my expectations. More powerful, and solidly functioning atomizer, which tastes SO much cleaner than even the all ceramic atomizers (at $1.80 each!). Sleek design that sells itself, and they're a tiny bit trickier to fill, but the filling process is also much cleaner (for me anyway), I don't spill it, don't overflow it, which is nice when the oil I use inside them isn't cheap! Also love the large rubber cap, and the mouthpiece. Small details, but the cap fits on nicely so it won't get lost, it will get put back after use, and the wide, glass, single piece mouthpiece gives a smooth draw, and has a clean look.
10/10. Will probably never buy carts that are any cheaper than this again.

These all glass carts are the best! Very clean taste as it does not have a cotton filter. The design allows for much more productive draws, blows big clouds if desired. Much better than the various all ceramic carts that struggle to work well with thick oils.

Highly recommended and I will only buy these all glass types from now on!
