I'm happy with my FT dna 30. It has no split in the top an d an adjustable 510 pin. Came with efest battery. Works great. Charges fast. Much lighter than my mvp2 or vamo v5. It claims to be manfactured by HotCig according to the stickers inside. Reads .1 to .3 ohms high, depending on resistance so the wattage also reads high. The resistance readings are stable so the wattage doesn't vary once set.
It doesn't have some of the problems I hear about with the Clouper. The wattage doesn't change on its own. It always wakes on one touch and fires on the next or after 2 seconds holding the button down. It hasn't self fired. The insides look good. Not much hot glue on the buttons and only around the edges of the board. The LED (visible through its own hole) does turn green when it is charged.
Mine arrived 1.5 weeks after ordering. That was a pleasant surprise. I expected about a month's delay.
I recommend the FT clone.
DITTO!!!
I also ordered from FT w. reservations but was pleasantly surprised. Found exactly what DrMarble here found here. Except mine actually seems to read accurately! I haven't tested enough to know though getting down to the .3-.4 ohm threshold, which is where it matters most...but from .8-2.0 it's been spot on! Could be a fluke.
Mine also came with an adjustable center post, something I haven't seen on any other DNA30s. Is it possible that they are actually trying to improve this version?!? ...nah...not FT...
