I just used this for the first time. I thought it was hard to adjust the angle of the bonnet, and collapsing it back to store it was hard as well. It felt cheaply made, unlike one I had years ago that was a snap to open and close. On this one, the column isn't adjustable up and down. When I sat under it, the heat wasn't reaching the lowest rollers on my set, and pulling the hood down was impossible. If I put it where I needed it before sitting down, it would snap to a higher position when I did sit down and put the hood over my head. Too tricky...I am returning it.
