I was just gifted two of them. At the $30 price point it's a winner (even at $45). Own REO grands and a CC is my daily driver. Using only for 24 hours so no idea on longevity. I can tell you it's not going to have the durability of either of those mods but, IT'S $30!
People might be thrown off by lack of VW but, it hits hard and consistently. I decided to use the provided rda and pre built
coils for testing sake. I found I needed to raise the
coils off the deck more to align with the rda air openings. Also, I like the air flow closed off to half using the top cap control.
I'm impressed. No leaks. Bottle squeezes easy enough. Liquid dispenses into the deck around the outer edge of rda through a number of holes and drains well. Battery cap is adjustable for any size variation in
batteries.
The mod itself is actually a identical to my CC in every dimension but, just a tad shorter. That's compact. 7ml 18650. Very lightweight. 5 clicks on/off.
There's a plastic "cork" that slides up and down the metal feed tube and appears to seal the tube when the bottle is removed. If so it's a pretty neat design. On the negative side could be something that breaks removing the bottle.
Things I can see breaking even in my brief time are definitely the magnetic bottle door. Flimsy. Someone over squeezing the bottle could possibly bend the metal feed tube. Other than internal failure that's it. Did I mention $30?
Oh and removing the bottle is a little tricky, forgot that. Also, I could see changing flavors being more of an issue with this design than a REO or CC. Thoroughly getting previous flavor out might be a little more work.
Rda is re-buildable. I could be wrong but, 510 doesn't appear to be adjustable or spring loaded so may not work with all RDAs.
I think it's a great introduction to bottom feeding, squonking or whatever you may like to call it...
