These balusters are very easy to install and come with the proper screws for attaching to anything 3/4\" thick or more. They are not near as flimsy as I had thought knowing they were hollow, so overall the rigidity is very good once installed with both screws. The finish seems to be very nice and I feel they will last a long while, but I will update that remark if it changes over the years. My only real complaint is that the screws supplied with these balusters apparently are not rust proof in the least, as I just installed these on an outdoor deck less than two months ago and I am noticing a little speckle of rust popping up on the screw head. A quick dab of paint should correct it, but imagine if you don't protect in and within a couple of seasons the screw heads may turn to solid rust. Other than that I would recommend this product and purchase again (except use my own exterior screw)
