OPKs.. Anyone try this brand??

Wondering which cheapie ovulation strips I should buy! Decisions, decisions.. 😂😩 can't decide from Easy@Home, Wondfo, BFPs, or Accumed. BFPs are a good brand but their 26$ for 40 expensive for strips. Wondfo is also a good brand & I could get 50 opk & 20 HCG for $21.99 but Accumed has 50 opk & 30 HCG for just $15.99! Not sure how good they are though. Anyone have any experience with Accumed or BFPs? I've tried Easy@Home and Wondfos are the same as these. They were good but I don't know! & definitely not getting the brand Answers, 20$ for just 20 OPKs? PSH, no! 😂😅 help a sista out, ladies!!
