I scrolled over that post several times without realising your asking to translate.
However this is more the usual "we are the best because our Product is superior which is because... " marketing vids - not a single word about the g80-3800.
But here you go, maybe someone else is interested in this to:
*cherry mx modules: unmatched in quality, longevity and precision. Since 1983*.
00.06- keyboards are an important part of modern communication. In regard of quality, longevity and precision cherry is brand leader for 30 years, also because of a proprietary development - the MX module.
00.20 This small component makes the difference and is symbolic for cherrys sucess. It is made since 1983 and its a further development of the "Schnappschalter" ( quick break switch ? *Action reset set* ? ) which was developed for electric typewriters. The Goal of the Inventor Günter Murmann had always been the high quality and longevity of keyboards.
00:40 Produced with the most advanced equipment at the location of Germany, up to 26 Million Modules are produced - each month. Already 5 years after the introduction to the market, MX Key Modules had a market share of 80% and cherry became the unrivaled Market leader.
01.00 Each single Module lasts up to 50 Millions actuations and is therefore up to this day without competition. One reason for this longevity is another development - the gold crosspoint contact. This principle is the reason for the excellent reliability of the MX technology.
01.20 3 Billion Modules have already been made, 80% of the production is exported to Asia. The MX Module is an export hit -made in Germany. The technology is especially appreciated by Gamers whose keyboards have to be especially robust and reliable.
01.40- Here again Cherry's sense of innovation becomes obvious. With the incorporation of a diode in each module it is possible to actuate all the keys at once - without blackouts. This is called "full n-key rollover". The MX Module is a top seller, reliable, robust, fast and long-living. Invented and steadily advanced by cherry - the Specialist for Computer input devices.
As a sidenote about that authoritative thingy...
The audio comment is rather official for german ears too, which is quite typical for german commercials or product information from companies doing business in the mechanical or technical sector. Don't know what they intend with that formal voice, maybe give the impression of precision.
