I've struggled to like the LEA after about a week of using it... And I know what you mean about the wetness. I find it's important to clean the tank cartridges and let them dry after a couple days use of each. That wetness comes from juice along with vapor running through the vent holes and up into the mouth piece, around the actual juice reservoir. It doesnt say so in the instructions, but it should probably note that it's important to cycle through the tank cartridges, run some water through them, then let them dry. Not sure if you're like me, but I tend to use one tank/carto until it's dead, rather than to switch between different ones... If you do the same thing, that could be why you didn't have the best experience with it. Between swapping tanks and swabbing the cone of the atomizer with a Q-tip at the end of every day or two, it guarantees you won't have the fluid running into your mouth. Using it heavily causes a liquid buildup within the atty cone, and that's where the issue can be resolved just as easily.
I actually love the Lea now that I dont have the wetness issue. It's perfect for taking it to work, takes a nice easy draw, it's quiet, doesn't produce a conspicuous cloud of vapor, people think it's a pen in my shirt pocket, and the on-off reassures me it won't fire accidentally.
For those reasons, I find it way better suited for my needs than I did the LEO. I feel like the LEO has to add a few of the features of the LEA to male the ultimate grab/go compact device, while the LEA could use a better feeding system, like the LEO.
Nothing's perfect yet I guess, but I've found the LEA enjoyable as a result of getting it to work right... It took a little trial and error, but I'm finally happy with it and urge you to give my suggestion a shot
