So I recently picked up some LR attys from TW for my tornado/eGo and I'm extremely happy with the vapor they produce while dripping. However, I'm finding that after about 3-5 days they develop a very burnt taste, even flooded with liquid. I'm on my 4th one that has done it, and what I think is happening is that the wick is getting burnt to where it no longer wicks and is burning? I'm wondering if someone has had a similar experience, or whether it is a TW atty problem, or knows of a solution to clean them to get them working properly again.
