Well I received my XPRO M80 today. I ordered last Friday and today is Wednesday, so it's pretty good in shipping. Also Kudos to 121vapes, they threw me some extra freebies including an ejuice bottle, 2 anti-slip rings, and a drip tip. Man, what a pleasant surprise! I guess I will order more from them from now on, and their stuff are cheap anyway. Thanks erikbal for the recommendation!
Anyway, I have been using the XPRO for a few hours. I tested it from 30w all the way to 80w, and the wattage output was the same as my sigelei 150's, so the wattage is accurate. I also like its extra menu like the clock, the puff count, etc. Although they are not really necessary, but it's nice to have something extra.
The buttons are responsive, so far I haven't experimented any failure-to-fire on clicks, and they are not as noisy as some other mods'.
The actual size of the mod is smaller than what I have seen from youtube. I was expecting it much bigger.
Finally, I am still waiting for my NI200 wires so I can't test it on TC mode. I know that it's burning the cotton from Mike Vapes' review (he burned the cotton without any juice on, comparing to VaporShark rDNA40 and vapor flask v3 clone), but hey for $53 on a 80 wattage box mod, it's still a great deal. When I receive the nickel wire, I will see how well it performs.
