Sadly not the result I was hoping for, but seeing the words "Not Pregnant" meant that it saved me from a potentially long day of umming and ahhing over whether there was a faint line or not. Having been pregnant three times before, I was sure that I felt all of the symptoms, so had almost made up my mind that I was. This (and another identical Clearblue Digital bought in my local supermarket) made it very clear to me when I was 1 day and then when I was 3 days late, that I wasn't pregnant and sure enough my period started on the 4th day.
I would definitely recommend, but probably I would suggest getting cheap supermarket/pharmacy tests for the initial test and then if you want it written in black and white (literally), then have this as your confirmation test.
The test itself is easy to use with clear instructions about either peeing directly onto the stick once you have removed the cover or for testing from a cup/container (you need to hold the test in the urine for longer if you test from a container)
If you don't give it long enough, then you will get an error code and you cannot use the test again, so it is well worth making sure that you give it enough time. Personally I have always found it easier to pee into a container and then test from there (rather than potentially missing the stick!), but each to their own!
