I've been using a Sigelei Zmax V3 Telescopic flat top for nearly three months and really like it. This is VV/VW and the telescopic tube allows use of single 18350, 18490, 18500, 18650 or 2x18350 battery configurations. I use 18650 at home and 18500 when I want a smaller form factor to fit a jeans pocket. The Sigelei Zmax voltage regulation is top quality, providing rock solid voltage regulation from full battery charge at 4.2V to low power cutoff at 3.3V.
I like carto tanks. With a syringe or needle tipped filling bottle I can refill a carto tank in about two minutes.
I recommend borosilicate glass (Pyrex) carto tanks from IBTanked for excellent quality and value. I recommend Varitube as a Sigelei vendor for the Zmax Telescopic because they will check and prep the mod and offer a 90-day replacement warranty.
