“The holes on this cartridge are really small and gunk up quickly. The first 3-5 hits are good but after that they slowly start “clogging up” and it becomes hard/impossible to even get a hit. I tried using 2 of these but could only get roughly 1/2 way through both .5ml cartridges before they completely “seized” up and stopped hitting. Only ordered these because the usual black tipped 2.0mm holed carts were out of stock but in the future I’ll just wait. I vape concentrate not vape juice so I can’t review how it works with those mixtures, only concentrate.”
