This is the best i ever owned. I love that it is all one piece. Just use...toss in the dishwasher, and done. No problems screwing, and unscrewing the base like other blenders. No risk of cutting my fingers. Love the placement, of the fan, for cooling so it doesn't overheat. Multiple settings. Ultimate is the wave motion. It pulls the ice, and or ingredients from the outside into a little whirpool in the center, so that all the ice or ingredients get mixed equally, without large chunks. I would definitely reccomend.
