So you really didn't have to press fit your sleeve? 
I had to press fit all three, the two that I received from Yosen (black and silver) and the one that I just got from FC (gold) They all showed up the same way ... not a huge deal as I was able to press fit them all, but still.. My zero turned up today
First thing I noticed, was the weight of the zero, gives a nice beefy well made feel to it, but could be a bit to heavy for some people though, for me it is a pro though.
I will say as reported, this thing does seem to hit harder than what it is set at, and mine the resistance reads 0.02ohms lower than what my coil is, so I have it set at 20 watts, where normally I vape at 25 watts, but also Nikki did say the chip seems to have a break in period, so will see if over time if that changes, but it is not a big negative to me anyway. Also even though the zero says it will only fire down to 0.50ohms, it was reading my resistance as 0.40ohms, and was firing it no problem.
I LOVE the fire button, there is a click when pushed, but it is very smooth, takes little pressure to fire, but with how the button is housed, no worries of it accidentally firing, I had no worries going out with it and just putting in my jacket pocket. I do wish it did have settings lock though, as have hit the up and down buttons a few times by mistake.
The only real negative I have about the appearance of my zero, is the screen is very slightly crooked, and is not centered in the window, so is cutting off the battery bar, as can see in the picture below (also can see the 0.40ohm resistance) but it is not a big deal to me, and if really bothered me, sure I could take apart and straighten it out, but doubt I will care enough to bother.
I did also get the black sleeve as can see in the pictures, I did not have to bend it into shape like Nikki has with her sleeves, and even though I think the black looks cool, as I thought it is one hell of a finger magnet, will probably look at covering with clear wrap later on, as that will bother me more than the screen.
Oh and mine, the key comes out easily, just use my thumb nail to pop it out, and I have used it a few times already to change the 510 pin, nice to not have to get up to search for a screwdriver
Personally I think the zero is very much worth the price tag, and love the ability to change the look of it so easily and quickly.
Its aluminum

After about 2 or 3 days I got used to it and I increased the wattage by 2W back to my usual. Not sure if its the Zero breaking in, or me breaking in, but that was my deal with it. But I vape it at the same wattage as I do everything else now. 
Oh, and whats up with the "authentic Smoktech"? FT can have that, thanks
Sweet .. As you said you may need to just clean the copper contacts. Break in period ... I will try to explain.
Not sure if I would call it a break in or not, but as I explained it to Nailz a week ago, when I first got it you all know that I said it had some punch. I adjusted my wattage down by 2W, but I never got any burnt or dry hit, but the throat hit and nicotine high was major
When I first got it I also used the USB port to recharge, but that lasted only a week and I mostly wanted to make sure that it worked. Now I just change the batteries out .. but I do like the there is a charge indicator light next to the port.
