Excelente inversión,buen precio hubiera sido ideal el lente polarizado ofrece mínima protección uv I hope this is helpful to someone. The positives include, according to my sister, "Theyre not as ugly as I expected they would be" and they do not put blisters anywhere on my feet. 5 if I don?t find another brand I like better. I take a 5 in trainer and 6 in shoe, 6 fits perfect It arrived in the packaging shown in my picture with the contents (minus the short bolt which I had already put on my bike) mentioned in the description on the Amazon website. I picked this product up last week along with the Chemical Guys Foam Blaster ($40) and Microfiber Mitt ($6). It is very difficult to install even though it seem easy in the instructions. This will be the only comment you need:-?does not fit 4 inch flex hose-?does not fit around powertec 4 inch couplers-??does fit the 4 inch powertec Y fittings-These brackets will spread apart 6-8 inches. Since there are fake birks out there, I didnt feel it was legit to pay the same price as the authentic ones and for it to not come in a box.
