My very old Black and Decker still made a pretty good seven minute frosting. But it was decades old.
I bought a far from top of the line Oster.
This morning, I made waffles. The Oster got better volumn on three cold and relatively fresh egg whites and got to soft peaks faster than the Black and Decker has for the past decade.
Util that moment I doubted my Oster buy. Not anymore.
