Product review (2 stars): I had to throw that one away- it's completely useless. I am using 5 bars
I bought 2 packages, since I needed 6 bars. I am using them vertically in a cabinet to hold cookie sheets and cutting boards. I twisted the first bar completely out to its full length to see if it would fit - and now it won't twist back in! It wasn't long enough for one cupboard and is too long for the cupboard I moved everything to. I had to throw that one away- it's completely useless. I am using 5 bars, but have to be careful not to knock into any of them, or they fall down.

I can't get them to stay super tight at any length, so they are working, but who knows how long it will last.
