I'm using three arms on the extra tall pole. Two 27" side by side and the third 34" above the two. So far, couple weeks, they've stayed exactly where I put them and yet are easy to move around. I looked around and I tried a few cheaper models (not even attempting three just for two) that just didn't get it done. While more expensive than others, this one delivers. I'm more than happy with this product.
