@ teacher: Sofirn SP10A V2.0
Some of the V 2.0 minuses:
SMO reflector instead of OP
starting with low (5lm) instead of eco (0.5lm)
lower output than v1 with 14500
lower output than v1( only about 170 lm with AA), the head is glued
it seems it doesn’t have memory when using AA (it must be confirmed by one who actually bought it)
