I recently bought a couple of "Clearomizers" from Valuevapor for a DSE-901. They are very good for vapor, but very difficult to fill and apperently need some sort of injector/syringe to make it easier. I have also considered the DSE-901 cartomizers and the T-tank atomizers with the e-go tank cartriges. Really looking for a DSE-901 combination that is easy to fill, small, and produces alot of vapor. Any suggestions? Thanks.
