I love my ego tank. I upgraded from a normal 510. The vapor production is good, best thing is not having to top off every 5 friggin minutes. As long as there's about 20% vg or greater in your mix, you won't need to worry about leaking. I love this thing so much, I got my brother who was smoking Newports at the time to buy a Ego Tank kit. He tried mine and just loved it. Can't smoke cause he's got a baby on the way.
For the terminally frustrated, and slightly bad news:
Okay, so the system is obviously not perfect. The biggest problem is the atomizer wick. The wick is unbelievably small. Note: You really need a McGuyvery spirit with the Ego Tank Atomizer) First you have to take of the needle plate. Directly under it is the wick. It has nearly invisible bird pubic hair. Gross I know, but it's so small and delicate I can't even touch it with my bare hands. I totally destroyed 1 wick from this. So it's almost like surgery for me. Using tweezers and all kinds of gadgets to remove and fluff wick and put it back in.
what happens if you mess the wick up. (buy another?) Hell no, back to the McGuyver spirit, I bought silica rope (its what the wick is made of) from Mcmaster carr for $4 I got 1foot so I could make my own wick. There's no replacement parts for the Tank atty yet. They need to mass produce wick and needle plate replacements. That's another story. Anyway, if you don't mind doing all of this, then you will have some great vaping sessions. Driving without any problems. Stealth vaping at work all day. It's awesome.
Now, I am planning on buying some Clearomizers and the MAP tank. I just can't use these at work, since the Ego Tank looks like a big pen or marker and I can play with it, keep it on my desk, and have it in my mouth without anybody looking weird at me. Clouds of vapor has the MAP tank. I'm not trying to be driving around or walking in the grocery store vaping (as I do now) with that thing.
Anway, this is my long dissertation about why I like it. So far, for a mostly analog look and feel there is nothing that compares to it. I love mods, but I really don't want to walk around in public with an alien looking device to my mouth and then blow out vapor.
Basically, unless you have a mod, everything else on the market sucks .... Battery life, flavor, vapor production, and ease of changing flavors absolutely can not be beat. Hands down.
End rant...
From what if heard, you are right, you do have to be a mcguyver to use these things. I just got 4 in the mail today. It seems the first one I got from an overseas vendor has a wick issue and needs to be adjusted. The second one from Cignot is working great. I'm going through the other ones to see if they are working properly. Thanks for all the input guys.
