I have the long version which replaces the removable cap on the eVic. Came with three "Atomizers", free. Bought it in a fever of "New Vaper Credit Card" syndrome. Arrived and well...
Have to say, I'm not enthused either.
How it went down:
Cleaned it out in boiling water, set it up and discovered that I like an overtone of burning polymers in my coffee flavored vape slightly more than the delicious taste of scorched cartomizer filler. But "OMG what a Throat Hit! I think it stripped the lining out of my neck! Where's my fillerless carto tank?" If you're a TH fan...
I then dripped the atty hoping for a milder "Urban Arsonist" flavor and gave it a full tank, alternating between my iTaste VV v3 with a iClear16 and the eVic ECA, both filled with supposedly delicious coffee ejuice. After a few draws the flavor of hate was replaced with a tasteless plume of mild dissapointment. I played around with the voltage on the eVic trying to match the awesomeness of the iTaste, but the eVic/ECA never went beyond "mmm, some vapor! And do I detect a hint of coffee in there?" for me. At least it didn't taste like a burned down coffee shop.
I also exercised my face muscles with effort to draw on the non-replaceable tip. While I like a tight draw as much as the next guy, getting a forced oral workout for my vape ... sucks.
By the time I got through the tank, I was ready to put it in the "Do not use - give to people I really dislike" box.
Cons:
My setup tasted like annoyance, after the "angry fire monster eating a puppy" flavor went away.
Loosens eyeballs from sockets trying to pull any air through the leakproof design. If you're eyes are really tight, this may be a pro instead.
Plastic tank... might be tank cracking and plastic or glue leeching issues in anything other than glass, and even some o rings are sketch.
Luckily, you get no o-rings with this product. I've discovered I really like the idea of a conventional o-ring over this innovative and highly engineered design.
Non removable drip tip means you're stuck with this tiny plastic nippletip. I want a different shape, maybe more draw? No, thats fine. Please make my eVic look like some kind of frosting dispensing nozzle device. And next time, please include buttercream frosting ejuice. At least I can imagine that what I'm vaping tastes like a delicious bakery treats and it won't use up any of my yummy ejuices.
Pros:
No leaks! All day, the ECA tank rattled around in my pocket and didn't lose a single drop! Even if I couldn't bring myself to vape it.
Looks awesome! (I have the long version which covers up the unsightly threads, making an eVic Hybrid and yeah, it's sleekly attractive to pastry professionals)
And it's got replaceable atomizers! They're easy to remove and replace, so when you find you've burned it out due to lack of wicking in a desperate attempt to taste a flavor other than "Volcano" from your vape, you can drop another one right in it's place.
I'd say to avoid this product. But if someone who dislikes you gave you one and you're handy with power tools, a desperate sacrifice to the Vapor Gods in hopes of modding yourself a divine miracle of function and flavor might make the ECA worthwhile. And hey, you can totally have mine...
