Love this equipment. It's versatile (lots of different exercises), space friendly (I managed to find room for it in my 800 square foot condo), and pretty easy to put together. The assembly, though time-consuming, came with pretty clear instructions. I must admit I had to check out the assembly video on the Marcy website a couple of times, mainly because my eyesight is bad enough to make it difficult to see the details in a couple of the pictures in the manual.
The number of different exercises that can be done on this gym is quite large. I would have appreciated a better description in the User Manual for some of them. In fact, it would have been nice to have a more thorough listing of the various routines the gym is good for. That being said, there's a ton of information on YouTube and other sites that will give you an idea of how to use it to achieve your fitness goals. I have a book describing many exercises to attack the various muscle groups, and I found that many of them could be adapted to use this gym.
The biggest complaint I have was that the packaging was substandard. The one box it came in was literally in two pieces held together by cling wrap and a lot of tape. I was concerned that some of the various pieces (340 in total by my count) might be missing. Amazingly, it was all there. I suspect the packaging issues could have been mitigated somewhat by packing the weight stack in a separate box. Just saying.
Overall, it's an impressive piece of equipment, very sturdy, and I expect it will be a staple of my fitness routine for many years to come.
