text: Design/assembly is sloppy.  The screws are not standard, they are hex head bolts and nuts and I needed to buy two special tools ($10.00 each) when the screws started to come loose after the first week.  I also had a nosepiece fall out after less than 1 month of normal use.<br /><br />Using standardized fasteners and replacement parts would be better for this product, I emailed the company for a replacement nosepiece and they told me to go thru Amazon.  That's not good service to your customer base, in my opinion.<br /><br />Such a shame, because they are excellent at preventing sun glare.
