The problem with those, that they easily attract our attention, as many devices which we reviewed in our journal, but we did not test those. We think that it is not worth to review and test all these devices. Eventually, these instructions and products are designed to easily attract our attention? But are they Swiss quality?
It is generally a good idea to use devices which are confirmed that they are used and are confirmed, that they have a good quality. Good devices which are tested and published in a high quality journal are to be preferred. We are not device testers. Test all of these at your own risk.
Our tendency is to build and test such devices ourselves, because we are Swiss quality, and we and to maintain a Swiss quality standard.
