Got mine in this morning, couldn't get it all set up until just now due to work until 11PM.
A little review; from pictures that I have seen, this is very similar (if not the same) as a GT Omega EVO. I've never actually sat in one, so I can't tell 100% one way or the other.
No missing parts. As stated above, some of the most important components are located inside other pieces of the rig for easier shipping. It was very easy to assemble, but I will say that the complete lack of instructions may frustrate a few people. It does come with a single picture diagram that shows where all the parts go, but it's not exactly the best way to instruct someone on assembling the rig. I just eyeballed it and figured it out in about 20 minutes. Based on rekki's experience, I am sure CNT will be very helpful if you need to give them a call or an email on setting it up.
The construction is very sturdy, will definitely withstand some use. I think the square tubing is great for modding later on. No paint was chipping and no dents were in the rig or anything when I took it out of the packaging, although it looked like UPS was not very careful with the package, the box was in pretty bad shape. That's on UPS though.
Mounted my g27 set to the rig, holes are already predrilled perfectly. Wheel height is adjustable a decent amount, probably about a 5-6 inch range. I'm a really short guy, and I like my wheel to be a little lower, so I have it set as low as it can go. The seat is mounted on a slider just like in an actual car, and it can be adjusted surprisingly far (for me, probably almost as far as my actual car seat). The shifter will move up and down in height with the wheel, as it is all mounted on the same "piece". My only complaint with the adjustability of this is that you have to unscrew a few bolts with a hex key (included) to adjust the height. The wheel tilt can be adjusted a TINY bit, but not really enough that I think would make any difference. The pedal angle, on the other hand, can be adjusted by a whole lot, and it is very easy to adjust.
The seat, IMO, is more comfortable than a Playseat Evolution (the only other cockpit I've ever actually sat in that wasn't a computer chair or something). No bar running up your spine (at least, not that I can feel). And the seatback is adjustable just like an actual car seat. The faux leather the seat is covered in seems like excellent quality for the price of the rig, and I think will stand up to a lot of use.
I tested everything out with a lap around the 'Ring in a GT-R Spec V. I don't particularly muscle around the wheel, shifter, or pedals, but the sturdiness of the rig was still very evident, absolutely no movement even when I was driving pretty hard.
So, PROS:
-Price (use the promo code in OP)
-Comfy, very adjustable seat
-Very sturdy construction
-Most components adjustable a good amount
CONS:
-Lack of instructions
-Needing a hex key to adjust some components
Overall, I think this is a fantastic rig, especially given the price. This is the first rig I have personally owned (my previous roommate owned a Playseat Evolution and g27, so I lived with that rig for over a year), and I love it. If you're looking for a first rig, this is definitely the way to go.
