We just got this and have only used it a couple times, but so far are very impressed with the quality of the machine. Very stable, heavy and feels secure.
I have had my plate for 1 week I am just sitting to do my workout as I am not ready to stand on it as when I tried it standing I needed my cane to lean on But i do feel a difference and I havent had bad leg cramps at night I am glad I made the investment
