I was expecting a normal thickness to the walls of these cans, something similar to the junk you find on a Walmart shelf. I was very pleasantly surprised to find they are actually thick. Very rugged yet light enough to be easy to use, a perfect blind of ease of use to durability. Compared to most cans they are far thicker and built much better, yet still not too heavy to carry and use. The mounting was super easy, and the locks ensure that they stay in place until YOU move them. Overall, a very solid system at half the price of other products of the same design.
