I've read a lot on here that the CBs are awful for accuracy. I currently have a stash of One Steps (which are apparently just as bad?) and I've got some FRERs on their way because we're going on holiday and I don't want to be stuck! This is our first month TTC.
Any other recommendations? I saw the Boots ones are supposed to be good but their reviews say otherwise so now I'm anxious to get them!
