I badgered and pleaded with my husband to get this for me for my birthday. I have now been using it with a treadmill for a month, for between 1 to 2 hours per day, and am feeling much more energized. I assembled it in about an hour. I am quite short so have it at the lowest setting and have found no issues with stability whatsoever. I use it with my laptop and a second monitor connected. Since I use a separate keyboard with my laptop, I have the laptop perched on top of a box so that it is at eye level while the keyboard is at a comfortable height for working. I love it, and have no complaints.
