Kaizoku, on TableTennisDB, Xiom Sigma II Europe also stands as a non-tensor. In fact there is clearly shown on the topsheet of the rubber itself that the Sigma II euro IS a tensor. Also take a look that T05 also stands as a non-tensor. And there are lots of other examples.
In fact, i think all the euro/jap rubbers that came on market after the speed glue ban are tensors(please correct me if I am wrong).
This is wrong, in a pedantic sort of way. Tensor is a trademark held by ESN, so only rubbers made by them can be "Tensors", and so only stuff labelled as Made In Germany can be Tensors (TM) by definition.
People tend to conflate "tension effect" rubbers with the name Tensor though, so this is a common error. Butterfly use the label "High Tension" as their marketing fluff, for example, to hint at the same thing.
(and this is without getting into the argument about if topsheet tension effect is a real thing or just a gimmick, of course)
But who knows - maybe TTDB are making the same mistake? Maybe their "Tensor" field is supposed to mean "tension effect" rubber, and should include stuff like T05? It's not clear - TTDB's popup help dialog on the Tensor field is a little ambiguous, which doesn't help. Regardless, TTDB is user-generated data, and so can't be used as a reference really.
