if you like the alien and cant afford GX350, then this would be the perfect mod for you. not only you can run it on 2 batteries like the alien, but you can also get 320 watts out of it with only three batteries, which is only 30 watts less than the gx350, but still plenty enough to run most new sub ohm tanks like the v10 coils for the tfv8 or the artic v12 and v24 coils. the interface is similar to the gx350 but in a smaller package, so it fits perfectly in hand or in your pocket without feeling too heavy. and with just the mod itself, it was 50 bucks cheper than the gx350, so you get similar power at a fraction of the cost.
if youre looking for a good 300 plus watt mod that isnt using a dna chip, and is around the same price as the rx300 *without the tank here on eciggity*, then this is the mod for you
