I am very impressed! I just assembled this Smith machine. The instructions were easy to follow. I did it by myself, but a second pair of hands would help. It's sturdy, but it has a small footprint, so I anchored it to the floor with lag bolts. I feel this is mandatory from a safety standpoint. There are concrete anchors included in the kit if you are installing the Smith on a slab.I've only put in a couple of sets of incline bench in just to demo my work, and it feels smooth, sturdy, and reliable.Two things to be mindful of: 1. Follow the instructions carefully, and pay attention to every detail from the diagrams. 2. DO NOT tighten every connection all the way because you will need a little play room to make sure everything lines up. After it is fully assembled, then make sure all connections are tight.All the parts and tools are included in the kit, but I did not use the wrench included. A 17mm socket and socket wrench is MUCH more efficient.I am very happy with this purchase. Buy it because I'm sure you will be happy too. Remember to plan to ANCHOR your machine to the floor.
