The heads aren’t Phillips, just clones right? I would expect the brush you are buying to be a clone also, or at best a good knock off. Phillips is pretty disciplined about their pricing internationally.
I buy cloned heads (but not the main brushes) and find them completely adequate.
I’m very doubtful they were legit, anything labeled third shifts are almost always fakes. I can’t find any soniccare on alibaba (just a lot of clones), they have stuff on TMall, but all the prices are normal.
