Just wondering if anyone else is experiencing problems with the Mig Cigs Clear Fusion tank? I ordered a package of three to try out a couple weeks ago. My first one lasted about a week before the tip broke off where it goes into the tank. Not thinking much about it, I put the 2nd one into service. Less than a week into it, with only one fill per evening, the tip again broke off. I have not taken these out of the home, and only use them to vape low mg vapor at night. The latest one has been filled less than 5 times. I'm just wondering if anyone else has experienced this problem with them? Thanks...
