The locking mechanism is a cheap piece of plastic that broke off completely the first (and only) time I used it. I don't know why the description has the word "tripod" as it is NOT a tripod screen. I knew that when I bought it, so it's not a problem for me. However, I could breathe on this thing and it would fall. It was impossible to get him to even stand on the carpet. I had to put it on a flat table and put a box behind it to keep it upright. You really need to make some swivel legs for the base. I ran it twice although it doesn't work for me because I really like how it pops out and rolls back. I like that it is small and very light and the canvas fabric is good quality, no wrinkles. It would be good for those who need a lightweight screen to hang as retractable screens are much heavier and more difficult to install. You can just hang it on a hook and get started right away.
