There has been some speculation about the cbfm and the persona contraception monitor, and whether the sticks are interchangeable.
Well I bought the persona monitor and both of the sticks. They are the EXACT SAME! They look the same, work the same, test for the same thing. The monitors are the same apart from the aesthetic design. The persona just gives you red and green lights (dtd on the red days obvs) whilst the cbfm gives you low high and peak.
Ladies, if you are considering the cbfm at £99, buy the persona at £20-30. Use it with the cbfm sticks at £20 for 20, rather than the persona sticks at £ 10 for 8!
