Nice product, does what it advertises. A few quality control issues kept me from giving it 5 stars:
First, beware of tightening the clamps too much on the upright support posts. The plastic will show white stress marks, a precursor to eventual material failure.The topmost clamps that fit into the ends of the top roller tube will not need much tightening to keep them from turning inward or outward, because the attachment to the roller tube will by itself hold the clamps in the proper orientation. Use just enough tightness to keep them and the roller tube from drifting down on the posts. Actually, once your installation is done, an extra screw installed through the clamp and the upright post will guarantee your roller never slides down.
Second, the last pieces secured on each end of the roller tube (the d-washer and the shiny cap nut) leave too much looseness. That allows quicker wearing and distorting of the
plastic bearing surfaces between the clamp and the roller tube. Before installing the awning, I put certain thicknesses of washers in that clamp-to-d-washer space to eliminate that way-too-loose fit. There should be the tiniest wiggle possible between the black support clamp and the d-washer, once that cap nut is tightened, so you can easily turn the washer(s) you added. If there is no wiggle room, it will be quite difficult to turn the manual crank handle to roll up or roll out the shade!
Finally, the sewing on 2 velcro tabs at the ends of the security screen was poorly done, making the velcro
only half effective. Actually, some velcro with more aggressive grabbing power would be better.
Vevor, I offer you my services in product improvement for a very modest fee!
