Well guys here are a few useful explanations:
1) it is more generic legal warning; at present not any lost an eye. In USA it is very common that factory add a lot of warnings on their products
2) grey colour: this was a decison of Martin. Despite that some do not like this colour (me too, in the very begginning) I think that it will be a success. At the end of the day do you think that the brown colour of coke was well acepted in the very begginning? Same hapened with our ukulele nylgut strings: white instead the traditional black. Yes; I received a lot of complaints and a few of insults. Now almost 90% of ukuleles employ white strings and they are millions. So give time to the Martin's myth to grows up.
3) the sound improve a lot time after time so do not try conslusion just after 15 minutes after the setup. Waii the next day.
4) We produce these strings here in Italy for Martin, so it is a real Martin product (made by us, of course). Generally speaking, many famous brands want their own brand strings (made form producer like us that manage their own extruder plants like us).
5) tension: it is a stark tension in comparation with the classical gutar sets. However I remember that they have designed a dedicated guitar with X bracing so the tension is the right one. I have played it a bit during the NAMM sow and I must say that I want to buy one one day!
6) Rubino versus Magnifico: the formula/ingredient are similar but not the same. Same with the ukulele strings we produce for Martin
Ps: in the picture at the NAMM show, Los Angeles at the launch of the strings and the guitar I have mentioned. ah, the guy in red is the designer of the guitar
