Summary First, after 2 months of trying, the device completely fails to prevent calcification on glass surfaces. Experiment: I really want this solution to work, so let's start with 5 stars. However, I could not find any credible scientific evidence to support these claims. Follow my progress as we have all the ingredients for a pure dough. Order, delivery, packaging - all great. I bought a few days before Prime Day and the company gave me the difference when I contacted them. This is a top model, so there's no reason to say: maybe you should try something stronger. 07/13/21 The installation took 30 minutes as expected. I used the whole spool and the spacing between the spools is a lot over half an inch; just a straight pipe. I attach a photo of the installation and a photo of the kettle "before". It was completely cleaned with a vinegar solution just 3 weeks ago. So we have a problem and a baseline for the test. The plan is to clean the kettle after a week and see what happens after 4 weeks. Pictures are attached) 05.09.21 see the last picture :( As a result, calcination returned. Maybe a little slower, and maybe the crystallization is a little different, but in general the device does not work to improve the situation with calcination turned on surfaces ...
