This is a hand-cranked bean grinder. It is very simple to use. Put the beans in, set the particle size as needed, and then turn the handle. A cup of 60 milliliters of ESPRESSO requires 18 grams of coffee powder, a wild turn takes about 30 seconds, and an elegant turn takes about 1 minute. I added a music box module to the inside of the bean warehouse, and turned the handle to drive the internal sound cylinder to rotate at the same time. The bumps on the sound cylinder sounded the shrapnel of the tooth comb in turn, injecting soul into this boring operation time. This is an out-of-function design, so is it a combination of design? According to the KANO model, this design corresponds to the "charm attribute", both: the user unexpected, if this demand is not provided, user satisfaction will not decrease, but when this demand is provided, user satisfaction will increase. This is a product with low technology content and high homogeneity, which should be considered emphatically. At the same time, in terms of marketing, if the media of product matching and short video are well made, there will be the possibility of dissemination. So that's all for this sharing. Thank you. See you next time.

The sound outlet is on the back.

Our aim is not to cause any trouble to users, and we can turn off the music if we don't want to listen to it.
