Clearblue digital opk -smiley face one

I have been using these this cycle and find them much simpler, no interpretation to be done, anyone else use them? What you think?

never heard of them is it a face that comes up?

Yes. You get 7 sticks in a pack. Each time you test is it does not detect an lh surge a cirle appears and if it does a siley face comes up. So you don't have to interpret the lines.

Sorry about typo's It should say circle/smiley face

I might get them been using First Response and at times its confusing, Im a simple person!
