free mixer

It is her birthday, as per the birth star. She is a teenager now. 

To celebrate, she is baking an egg less cake with her grand mother, from a youtube recipe. 

She is making whipping cream from some powder and milk.  After she and her mother tried with the mixer where the crank wheel needs to be turned as fast as you can, they turned to me. I was grumbling that this is enough after a minute. Then she showed me a video of someone mixing the cream - it was a hand mixer which was automatic, battery operated maybe. I said see, we should have had that than this much effort. 

She says she has "a energy efficient, climate friendly, low cost - free mixer" - me! That too came with buy one get one free. 

I said I had enough, get it done with your mother. 

She says - should have expected only this much from the free one. And gives it to her mother saying - the one bought with money will work better!
