I've gone through 2 Itaste VTRs, broke one and one's semi broken, I really love the form factor especially the recessed tank but having broke the battery door on one and having another that has always had issues with some tanks (I have a couple kanger aerotanks that work fine in other APVs that won't fire in this VTR) and in general has never worked 100% so I was hoping for some suggestions for a replacement APV. Taking flattop 18650s is a must I really don't want to replace all my batteries right now, and I'd strongly prefer a similar form factor (box mod, recessed tank)
