i must disagree with the above post, although valid points were brought up.
the tobh is impossible to find (new or used) because it's the best. it may be difficult to learn how to build, but once it is set up the vapor production blows every atty out of the water, without adding random holes in the cap reducing the flavor to nothing. (cough mutation x / plumeveil cough).
the top cap plus a normal 510 wide bore drip tip already produced crazy vapor, but with the tobh slam cap or the chuff enuff top, vapor production simply can't be touched.
as far as looks, i realize it's a factor for most. what i can say is the tobh v2.5 looks best to me, because there are no words on it, just a symbol.
as with anything, there are downsides. The first biggest downside is obviously it cannot be purchased new. Be patient, chances are a v3 isn't too far off.
the tabs are goofy yes, but they have inspired me to do some out of the box builds that surprisingly work just as good or better than a traditional dual coil like everyone is running.
the airholes leak like a sieve. As with literally every other rda with this layout. you learn to drain the atty before you put it in your pocket, problem solved.
the orings are not fit for a tiny infant's fingers, i suppose one could view this as a positive if they have a tiny infant. they do take some wrestling with, indicative of a device that was built by a vaper, for a vaper. Not one of the 129,943,589 atomizers produced this year from the bandwagon riders trying to make a dime before the whole thing pops.
now the market is well beyond saturated, rdas have moved into the 90-120 dollar price range, and they are all just copies of themselves. I'm good.....
to op: hold out for tobh v3 or find one used.
