I love my mixer, but I wish I had not bought the 5qt tilt model (model no KSM105GBCMC). The plastic piece that threads onto the bottom of the bowl has been problematic since day one. It constantly comes loose! My husband and I spent so much time and energy trying to get it to work properly- taking it on and off, tightening and rethreading it. Despite our best efforts, it came loose while mixing some cake batter and the glass bowl broke! Terrifying. We’ve since ordered a ceramic bowl replacement... which looks gorgeous, but is loose and wobbly and feels unsecured. I’m a nervous wreck every time we use it! Plus, the whisk and paddle attachments do not reach the contours of the bowl. Overall, I’m really disappointed.
