Query: Bad Blender / Bad Warranty

This blender is unreliable and does not work well for smoothies (our main use for a blender). When the cutter assembly broke (after ~20 uses) I contacted Cuisinart about a warranty replacement. Since the blender was purchased as a gift (from our wedding registry), we did not have "proof of purchase" and Cuisinart did not honor the 3-year warranty.We purchased a replacement part from CuisinartWebstore.com (~$21 with shipping) and got through another ~10 uses before that cutter assembly broke as well. This time with a proof of purchase in hand I called cuisinart customer "service" again only to learn they do not warranty items bought at the webstore (i.e. the replacement part had no warranty).If we could rate a company / brand here as well I would give one star to Cuisinart (i.e. Conair) for their shoddy product quality and poor customer service.
