Although I am excited about the associated event, I find this accessory very unnecessary and rather overpriced. I bought the same hole Stecher at Hofer (Austrian Aldi) for 2.99 euros before this accessory was delivered. This works even better than the hole maker of SWISSINNO and the Diameter is also the same. The search bar is I think the most unnecessary product at all, this can be replaced by just about any wooden sticks. (Eg Chinese chopsticks, pens, stiff wire, knitting needle, etc.)
