To be honest I didn't realize how much I needed this blender. The blender that I've had for probably over 20 years just kept chugging along. It worked, but it took a little effort on my part. Using this Hamilton Beach 10 Speed Wave maker Blender for the first time opened up my eyes. It's kinda like getting new tires on your car when your old tires are getting worn out. The difference is so obvious. I'm not going to lie - this blender will be mainly used to make margaritas and the wave action makes it easier to break up ice cubes. At 575 watts this blender justs powers through the ice and leaves virtually no ice chunks! My only regret is not getting this blender a long time ago!
