Waring WPB 01 / 04 / 05 / 09 2-Speed Blender

I tried this based on other reviews of Waring. I make a blender drink with frozen fruit and it can really bog down a blender, many blenders just spin without mixing the ingredients together forcing the use of a wooden spoon to help with an occasional resulting mess (that is what happened to this one with much motor burning smell). I took it back to Macy's. Get a Hamilton Beach Wave Power. It is all in the shape of the glass, it blends by spinning and by the shape of the glass mixing from the bottom upwards.
