T3S has a tight draw

[glovedo09]

I have a few MT3Ss and a T3S with different flavors in each. At first they were perfect!!! The inhale was rather "airy" compared to other clearos. However I have found they now have an extremely tight draw (almost pulling back) if that makes sense. And its 3 or 4 out of the bunch. Am I missing something or is this a known issue?

I just bought two and one works great, whereas the other is exactly as you described.

Customer support from MBV recommended I replace the coil even though it was brand new.

Coil could be the issue also if that doesn't work. You can bore out one of the air holes that worked awesome with mine
