I've heard some good and bad about the dna200. Some people have been saying their mods are just quiting on them. Not just a random thing....or is it???
Actually, there are LOTS of "cloud chasing" people out there rushing to buy 200 watt mods. Note that most of these folks probably shouldn't be trusted with a double-A battery. Most of the time, their mods quitting is not a "random thing". It is SERIOUS user error. Better if their mods "just quit" when they screw up, rather than having those mods go out the hard way (in a fiery maelstrom).
Here's how the "cloud chasing" game is played. You'll fork over wads of your hard-earned cash for some beautiful, 200 watt monster and you'll be so proud to be the master of such a powerful beast (even though you'll rarely, if ever, turn it up past 50 watts).
But within a year, one of your friends will come strolling down the street sporting a brand new 500 watt steam machine. It'll make your puny little mod seem like an e-cig with a dying battery, and you'll quickly hide it in your pocket in shame.
But don't worry... you'll rush out and lay down some bankroll on the brand new "Kilowatt God-Mod" (which doubles as a stun-gun, and will also jump start a car). You'll go looking for that friend, and when you find him, he'll cower in fear at your new found power. You'll blow clouds so big that the National Weather Service will issue an alert for your state.
Jump ahead a few more years, and the arms race will eventually produce megawatt and gigawatt mods. You'll be salvaging old springs from trucks to use as coils, and wicking them with Japanese cotton bathrobes. Of course you'll need a pickup truck to haul all the batteries and the 50 gallon drums of juice.
Or you could just decide to skip the silly arms race which is "cloud chasing". Pick out a nice little 50 watt mod, which will be just fine for pretty much any sane vaping activity you're ever likely to engage in.
