Has anyone used this OPKs

𝔇𝔢𝔢🌷

Im currently on my TWW but if things don’t go as planned, I want to be prepared for next month. I saw Surearly digital OPK on amazon and it has better reviews than Clearblue and they are nice on the pocket too. Has anyone tried the Surearly brand? Im also going to buy ovulation test strips, the digital opk is to confirm. Any feedback is greatly appreciated. 😊
