Electronic Pregnancy Test - Anyone tried it?

[M2T]

I saw the advert last week and am curious.... I s'pose it'll get rid of the problem of wondering whether it's a strong line or a weak line.... it's just either:

Pregnant
or
Not Pregnant

What do you all think of this new test?

I think that at £14.99, including 3 test sticks and they DON'T sell refills its a bit of a rip off. Plus the result only stays visible for 1 hour, so you have to use another stick if you need to show someone else after 60 minutes.
