Kaidomain 20mmx20mmx1.5mm copper board for luminus sst-90 - any good?????

See post #21

I have not used any sst-90 from the purchase I made yet.

EDIT: I just worked out OP is talking about copper star only. I will tell you tomorrow I bought a MT-G2 that happens to be mounted on the same star (even labelled ‘sst-90’).
