Altogether, I find the way you have presented the companies and how you have examined the diverse technologies short, succinct as well as precisely summarized and elaborated. What I also like is the presentation of the companies’ future development. What would be especially important to us is a more comprehensive consideration of current production and its prospective development, along with a corresponding assessment of volumes. I like the study very much and overall it is a job well done.

“Enormous data reliably analyzed”
It’s surprising how the enormous data and even the widely accepted rumors could be collected and analyzed reliably. More surprising is Bernreuter’s expertise in extracting explicit and quantitative essences from them.
