Littlebird4 Gerenic Toothbrush Heads Compatible with Braun Oral B Sonic Complete & Vitality Sonic (8)

Will this fit oral b sonic complete type 4717?

Would like to know this brush head where is product coming from , where is the country made in??

do these brush heads qualify as "soft" by ada standards? the last ones i tried were so hard they could not be used.
