I purchased this unit a few weeks ago and am really enjoying it. Many moons ago I was really into strength training but currently my goals are more geared towards leaning out and getting that narrow fit physique and that seems to be what this system is good for. I have some wrist issues and I find that the ergonomics of this set up doesn't seem to affect those issues as much as free weights. All in all it's a good setup but include a seperate cardio portion and it would probably help to have some free weights available to mix in to your workout as well as in certain situations the included rods aren't enough and upgrading the power rods can be pricy. Also, it's probably pretty safe to say you could save a lot on your initial purchase if you buy used. Performance Good depending on your goals. If you are looking to be a hulking beast, save your money and go with free weights. Ease of Use Steep learning curve but once you figure it out transitions between exercises and picking proper tensions is a breese. Durability Well made, and power rods come with a lifetime guarentee which eases the mind a little bit when you are bending them to the floor. Design Pretty ingenous. I like that the system is quiet and smooth.
