Havent had it long. Only 2 weeks now so this review will only be based on initial thoughts of product assembly and workmanship. Assembly was quite simple and straightforward. Material seems to be good and built well. My one concern is on the nut and bolt system as heat will be applied to them and if the expansion and contraction will cause them to become loose over time. Especially the nuts and bolts at the pivot points that have back and forth movement from lifting and lowering the screen. Time will tell but overall I am happy with my initial purchase and it looks good.
