They are good tests but please don't crack them open. They have a slight indent where the dye sits if it's a postive test, when the test is opened this indent is visible leading the tester to believe it's a BFP when it may actually not be. I've been a victim of this and it's not fun. Please update us though
I found them quite hard to read - really faint line was hard to see behind the clear plastic bit. Did get a result a few days early though. Actually found asda early tests better, apparently less sensetive but showed a clear line much earlier for me, and earlier than first response. Nice and cheap too!
So just realised miscalculated AF it's due Sat not today took the other early response test this morning and was invalid so took a Sainsbury's one not sure if it's the start of a positive or an evap line was 5 mins after doing test x
