The lens shade arrived in excellent condition, very well packed. It's made of stiff plastic, much more sturdy than I had anticipated. Color matches my Celestron CPC 11 perfectly, as does the company lettering. It attaches quickly; just wrap it around the end of the scope and snug it up. Removes easily. Takes up very little space as it rolls into a tight tube. It does indeed help prevent dew from forming on the main lens of the scope, and it seems to help with observing as well by helping keep stray light out of the scope.Overall, it's a basic, sturdy and effective method of extending your observing sessions by keeping dew from forming on your scope. It's very easy to use, well made, and the price is reasonable.
