Difference between an internet cheapie and a FRER!?

So, I am on CD 26, AF was due yesterday. No sign of her. I’ve been using internet cheapie tests that I bought in bulk on Amazon since 8 DPO. All tests are super negative. I tested this evening on an internet cheapie and still super negative. I’ve recently read reviews of how crappy internet cheapies are. I went to Walgreens and purchased a FRER, but am scared to take it for fear of a BFN. What are your personal opinions on internet cheapies when compared to FRER?
