Don't trust these people! I wanted to save money, but a miser pays twice. I had to refine many unpleasant things: crooked screws, sagging window sill, drainage holes clogged with chips, mounting brackets and canopies leaves much to be desired. There are no questions about the materials, but the execution of the work is disgusting. Mounting foam prevails over the construction, which raises questions about measurements. I spit on your business!
