Yeah, I really like the IPVD2 I have had it since the day they came out, nice small form factor and just works in both modes fine. I get great battery life with A brown LG battery in it. I have the Snowwolf, heavy fingerprint magnet but performs well, Dont bring it out much, Just too heavy. If your looking at these go with the 1.5 model It has a few upgrades that make it worth it. I also have the Smok Xcube, that I would pass on, has some cool features but is a pain with the menu. the Sigelei 75 is nice but find the D2 has better battery life and just feels better holding. I really like My Le80 for a standard coil set up. Hits hard and is easy to regulate. I have the Ijoy Asolo on the way in a few days. Depends on what you want out of mods, many affordable good ones. are you looking for strickly Temp control ? and what do you prefer 1or 2 18650s ? Sorry just seen Dual battery mods.
