The whole LT thing has been fun to watch/read. Guess what, I have all the hits and frankly, the LT works. If you've ordered one, it'll work. Its not rocket science. Want rocket science, then you probably should start designing electronic circuits. Perhaps look into DC-DC converters.. There's a lot already out there and I'm sure you can find all the stuff on ebay to build one for about $5 as long as you're willing to spend all your free time fitting it all into a special threaded aluminum tube sized properly to accept a battery capable of delivering the amps/volts.
But! if you're just wanting a good vape, the LT can deliver that. At a price point offering what some of the higher price spreads offer. But, envy value is pretty low. Although, it does look pretty good. For you folks just wanting a great vape to satisfy that need or ??? then the LT will do it it. Get a good 3 ohm cart and fill it up with what you like, dial it in, and I bet you'll be happy. If you want to compare numbers, then you'll never be happy. I'm vaping right now on two (2) LT's, one with a smoktek DC 1.7ohm XXL and the other with STD 510 cart and guess what, they're great! Doin the job! They'll run all day without a battery change.. If you need 10.8volts, you probably need to re-evaluate your requirements. If you're seriously vaping at 6v, then the LT is NOT, NOT, NOT, what you want/need. What I've found works best for this is a big square battery under the hood of my truck but does require special connectors that are hard to find.... These connectors seems to be about 3/4" in diameter and HEAVY. Way too heavy and bulky for me.. In fact 'that' PV weighed in at 36 pounds and I was facing getting hooked on steroids to haul it around.
My recommendation, learn to 'use' the PV you HAVE and find a combination of carts/juice that work for you. If you want to chase numbers, then, have fun also but, realize, you're chasing numbers and please don't look 'up' to those of us that just want a great vape. I thought this was what this was all about anyways. A healthier alternative.
Bottom line...... the LT works as long as you're not counting electrons.. But, if you're counting electrons, you'll need something else, Ehh? Maybe the new nuclear fision XYZ that will also glow in the dark.
Very good VV's... Provari, Rubicon, Madvapes DIY's, Darwin, and oh yeah, the LT... I don't have a Darwin, yet...

Reason, I don't want a unit with an integral battery.. Only reason I don't have one...
If you've got an LT or one on the way, get ready..... you're gonna or already having a great vape! If you want to...
You can make ANY cart/juice taste like crap. Challenge me! I know, I have... disclaimer, sorry, I'm not a PRO reviewer or vaper... Just a user.
HAVE FUN WITH THIS! Thats why you're here....
