This is my 5th Cthulhu AIO and second rev 2. I purchased it as a backup for my current rev 2. I've been using these mods for a few years now as my daily vape. They do not last forever and take a beating. Two of my rev 1's have failed boards, each lasted ~2 years. The third rev 1 has a positive pin that has loosened and sunk down, making a terrible connection. I will probably combine parts to revive one of the old rev 1's for a spare. That's okay, I love them for their all metal construction and compact size. The rev 2 is certainly an improvement. I vape simple 30 GA SS316L coils at ~1.2 ohms in temperature control mode. The rev 2 seems to have better resistance stability. The adjustable positive pin in nice as well. I really like the new drip tip. You don't know how many time I banged the rev 1 metal drip tip into my teeth while driving an hitting a bump in the road. I cannot comment on the included tank/RBA since I use a Yec Studio boro tank VWM Dope RBA. If you were on the fence about purchasing a Cthulhu AIO, go for it.
