Very robust material, especially thanks to the quality of the massive glass bowl. Very reliable for hot preparations. Finesse flawless texture. Takes up little space for storage because there is no built-in motor (need to adapt it to a Kenwood Chef-type machine.) Beware though, it takes a minimum amount of fluid for mixing begins. The white plastic at the base of the propeller turns yellow with a little hot foods containing carotene ... only minor drawback. Besides this propeller with its white plastic are the only parts that do not go in the dishwasher puique the mechanism is visible from below (washing in the fountain without turning it). Everything else goes in the dishwasher. Overall very satisfied, I do not regret this purchase.
