First Response Ovulation Test 20-pk.

Rating

The tests are exactly of the same quality as the individually packed tests, however don’t have the caps and all 20 of them are packed together in a zipped bag. Once opened they have to be used within 20 days. If for some reason you have to test for more than 7 days, they are pretty good deal. Otherwise the regular 7-day pack is your best bet.

They were always easy to read for me (I assume it may vary by individual hormone levels) and left no doubt when the surge is occurring. I have tried using Clear Blue before and the First Response were way easier to read.
