Alto Sax Reeds review for ASIN B0CRXL1TMW.
Hans says in the review "This time I went further in my evaluation and took some measurement with this batch and as comparison a Vandoren Java filed red cut 2. If you go to Vandoren's page you can see the measurements of their reeds. All have the same measurements. I measured my ,which is already used and the stock is compressed through the ligature. My measurement (second picture from the left) incl measuring error +/- 0.01 confirmed the dimension Vandoren claims.
Clearly Hans is promoting Vandoren by repeated reference. Vandoren is a very big brand.
Hans goes on to say: I also went to the GKW store. They offer 5 products: Saxophone/clarinet reeds (one strength), a trumpet, a clarinet and a trumpet mouthpiece. The claim the have along tradition of education. But the store is rudimentary and looks like set up only for a short period.
Firstly, it is a new store that I had made. It is totally irrelevant and slandering me. Secondly, he is committing defamation of character on "my educational background" based on the fact that I am a poor school teacher that is establishing their Amazon store.
Last, I am attaching pictures he attached to the review. Nowhere does it say my brand name. Just a tool that would likely be used by a competitor or manufacturer.
