[Variatio]

Interessant:
"Tenergy 05 and Tenergy 64 have the same spring sponge, whose density is about 48.0 degree. Butterfly tells that their density of sponge is 36.0 degree, but the standard of Butterfly concerned with sponge density is quite unique. The difference between German standard and the standard of Butterfly is something like the difference between Farenheit and Celcius in temperature. So be careful not to think that Tenergy 05 and 64 have soft sponge."

Soviel dazu, dass nur die Chinesen komische Haertegrade benutzen ...
