I used a couple of corner braces/brackets to reinforce the bench. Wish I had read Simon Edwards review first, i also read the two the description as two sets of two, the images suggest the same, but its two sets of two single layers, NOT TWO SETS OF TWO. I have dropped my water usage tremendously due to this device. i feel like i am wearing no shoes when i wear these flip flops! It wasnt directly exposed to the rain as it was installed under the rooftop of the gazebo, but was exposed to moisture and spray. Would highly recommend these Dream Pairs sandals. Comfy and cute I got my first Tile free last year with a promotion and loved it. Nice looking shoe but WAY too big. Well I was correct.
