My friend got me this on my birthday. I always wanted a glass bowl on my Guava Glaze Kitchenaid Mixer. I just loved how it looked but when I used it to make cookie doughs it won't twist to get removed off my mixer. I did everything from spraying the bottom with cooking oil to placing them down the floor and twist it with your hands while your legs keep them at one place. It didn't work. So I had to wait to my husband to come back from work and when he tried to remove the bowl from the mixer it broke and scratched my very dear pink mixer. I'm telling you I cried and kept thinking about it. I hope they would have make the bowl stronger. :-(
