OPK, internet cheapies or Clearblue which is better?

[Pipbin]

I've been using internet cheapies but only ever got a faint line.

What do you use, what do you recommend?

I used to use cheap tescos and wilkinsons ones until I discovered the digis and now I would never go back! I found cheapies hit and miss but always get a clear on the digis, and being able to use fmu is a huge advantage. Buy a box of 30 off amazon and they last for months, I usually get away with only using 4 or 5 per cycle, starting on day 10 (I have 28 day cycles). The box will tell you to start earlier but after a few months you will know what's normal for you and you can cut back.
