hello - Personally i like the digital ones best. Because with those there is no messing. I have used most over the two years I was trying - probably on average 4 a month (sad I know) and if I bought the cheaper ones, I would never trust them so would end up going out and getting the clearblue ones anyway - so bit of a false ecomony- for me anyway, but I think everytime I weed on one, I lost a bit of my brain, so that why I would buy so many every month. Good luck to everyone this month xxxxx Forgot to say - that the amount of brain I lost when I was trying hasn't grown back yet as I have done tests since being pregnant, like the night before my 12 week scan - just to confirm I hadn't dreamt the whole thing!!
