I wanted to wait until I had this reformer a little bit before I reviewed. So far it is pretty steady. it is definitely not for tall people so I would not recommend for anybody over 5'9", honestly. I just got certified as an instructor and that meant I went on the wait list for any classes at my studio. I figured I could give myself my own flow if I just had my reformer. unfortunately, I did not have a dedicated room. I like that this reformer is foldable. it is not very large, so I have ended up keeping it unfolded for the time being in the corner of the office. it actually does not take up much room and it's very efficient. I did not like the straps it came with so I did buy straps from Amazon to attach to it. it was a very easy switch. once you adjust the ropes for your size it turns out to be quite a handy and quick reformer flow.
The jump board I just used for the first time today, and it was a great workout! It's actually a lot more padded than the ones at my studio so the shock to my joints is not that bad. the foot bar is a little creaky but it has not given out on me, and I have been doing down stretches, flying lunges, and flamingos. All in all, I'd have to say it is a pretty steady machine for what I paid. if it even lasts a year, it was worth it. I paid under $400.
ps... I find that I just used the Springs instead of the cords. you have to remove the foot pad to use the cords and it became too much of an issue. I found I had decent enough resistance with just the springs. If I really wanted to take it up a notch, I would add one cord to whatever spring setting I had.
