I received my Cloupor DNA30 clone today, and I have it sitting here beside the FastTech DNA20 clone. I'm going to send the FT back, and am awaiting an RMA from FT before it hits the mail. But while they're both in front of me, a few observations concerning the differences between the two...
1) Machining is ever so slightly better on the FT model. No swirl marks at all in the drip well or button depressions. The Cloupor is not bad at all, but there are some swirl marks in the drip well and fire button depression. Anodization is also slightly better on the FT model, with some slight color variations visible on the Cloupor clone. Not bad, but visible.
2) Buttons are MUCH better on the Cloupor clone than the FT. The FT buttons don't protrude as far outside the case as the Cloupor buttons. The Cloupor buttons are also "clickier" and easier to push. I had to use my thumbnail or point of my finger to even push the FT fire button. It got looser over time, but was still embedded a little too far inside the case.
3) The Cloupor version is a couple of millimeters taller than the FT version. Could be due to the top piece not having the split.
4) Tanks sit more flush on the Cloupor version than they did on the FT version. Both were perfectly straight.
5) Corners are more pronounced on the FT version. The Cloupor version has more of a curve on the corners.
6) The Cloupor clone still has the wide pin in the 510 connector. It is even wider than the FT version, and I thought it was bad.
7) The screen on the Cloupor version "blinks" a bit when going through the dimming process. The FT chip seemed more consistent when it was dimming.
8) Wiring is neater on the FT clone. The Cloupor clone has the plastic window (which I've not removed yet), but I can see a wad of wires inside the Cloupor that wasn't there on the FT.
9) The FT was always high by .01 or .02 on ohms. The Cloupor is actually matching my Vamo perfectly.
10) I could see the red and green light on the FT clone through the USB cutout. There was some space there that the light was able to get through. I cannot see the light at all on my Cloupor. I *think* I see a red glow through the screen, but will need to get in a darker area to be sure.
11) Finally, the timeout is longer on the Cloupor clone. The FT sleeps at approximately 40 seconds, and the Cloupor sleeps after 2 minutes.
Overall, I'm happy with the Cloupor so far. I have to do something about this pin soon, though. I may try to pull it out and see if I can file it down. If that fails, I'll order a FatDaddy 510 and just be done with it.
