I purchased this mixer as a replacement for my 21-year old Courant hand mixer. I used my old mixer for everything, including heavy batters, and it always held up well. Although it was still functional, the switch wore out and I couldn't turn it off. The only thing I dislike about the new mixer is the adjustable cord attachment, which actually makes it more difficult to handle. Despite this, I am very happy with the overall performance of the mixer.
