These bags are great, they're made of very durable material. I used to have to make multiple trips because I can only carry few of the microphone and the speaker stands at a time. And when you try to put them onto a cart, sometimes they will roll off while you are pushing the cart. These bags allow me to consolidate everything into three bags and they even stay on while you're pushing the cart. And the best thing is you only have to make one trip :=)
