What is the best OV test strips?

I have used the First Response fertility strips and the lines that need to match are so hard to read. Sometimes the color looks to match and other times it doesn't. I have seen that ClearBlue offers the digital smiley face one, but much more expensive. Anyone care to share their reviews on these?

Hey shoegal! I've never tried the digital ones, but it I guess it can't be more clear than getting a smiley face. But ms320 had a pretty good idea here a couple of days ago. Since the digital tests are so much more expensive, she would use regular OPKs until O and then a digital one if she needed to confirm. I though that was a prety good idea, so I though I'd pass it on...

I have also never used the digital ones. I am inherently cheap, I can't help it. This month I have used answer brand ones, that you get 20 strips instead of 7 tests. They only last 30 days from when you open them, but for me, that was a good thing. It made me continue to use them after I figured I had missed the surge and was outta luck. This morning I got a positive-first one in many months of using other kinds with no positive. I apparently ovulate late and have a shorter luteral phase, which is all news to me!
Good luck.
