I like it. It took me about 5-6 hours to assemble. I'm mechanically inclined. The video assembly instructions are simple to follow and detailed with 3D diagrams. The parts in the box are not numbered so you need basic cognitive skills to match parts to pictures. Follow the hardware in order of the steps. Cardboard #1 comes with the hardware for all the first steps, cardboard #2 for the next set. etc.
I put one weight on upside down because I wasn't paying attention and had to disassemble some things at the very end to flip it over. That was no fun. So definitely pay attention at every step. Make sure the cables are routed properly. It seems like you skip over a step or two, but that is for a reason… they come up later in the assembly.
My only complaints are that the range of motion is a bit low. I'm 5'10" and can't get that last bit of push in a few of the exercises, like the butterfly, even with the back seat all the way forward, I wish the bars went back a little further. A couple other motion range issues. I think if you're over 6' or have long arms this might not be for you.
Second complaint is the cable/roller system is a tiny bit noisy. I will probably add some light lithium cable grease where they contact the rollers (of which there are many).
Other than that I like this machine. It's versatile and you can make up your own exercises on it. My wife is getting the hang of it too, but she wishes there was a good leg squeeze exercise for the inner thighs. I guess you can't have everything for this price.
For the $600 I'm happy. Well engineered, well thought out, and relatively easy to assemble if you have kinesthetic intelligence.
