The California Fitness Rower is an excellent machine--as close to a Concept2 as you can get, but less than 1/2 the price. I use it every day, 7 days a week--it is sturdy, easy to assemble, and has a shelf to put a tablet or phone for use while working out.
Im very satisfied with my purchase of the SM-4033, I bought my first one 2 years ago and loved it so much I bought another one as a gift for my brother. I find this smith machine to be made of quality parts, this machine is very sturdy and reliable, the cables have held up well over the years, I use every feature available on this smith machine. I love all the different exercises it allows for, saving space and money from having to buy multiple machines to get all the functions that sm-4033 offers. Im a disabled individual, and this machine allows me to adjust for my injuries, when there are days I can't bench due to injury, im able to use the built in pulley system to work the same areas of the chest, also this smith machine with its built in safety allows me to work with heavy weight without the need of a spotter. I couldn't be more satisfied.
I bought it a year ago and I enjoy using it.
