really cant give a lot of advice seeing all mine are complete failures. the only one that actually worked and i use daily is a syringe mod.it is a 3 mil. syringe that replaces the clear tube on a clearomizer.it is a little wider diameter which lets it wick much better, and the clearomizer tubes break very easy.look on youtube for clearomizer syringe mod by shanaburkholder she has a step by step. let me know if i can help any more.
