Digital opk? Clear blue?

I have seen these advertised and they look great, I find interpreting the lines on regular opk a bit tricky. I just googled and they are more than $50!!!:o This is just for 7 days of testing! :o:o so my questions are...

Can you buy replacement / refill sticks? if so where and how much?

Has anyone used them with success?

Are there different brands?

Thanks :)

:bump:

Anyone?

Hi Amuanet
My DH seen these advertised the other day and said I should get them!! But the price is a bit much.
As for replacements - I don't think that there would be TBH! Have you googled to see if there is anything?
I think they are fairly new so not many people would have used them but the smiley and sad face seem pretty cute!

Thanks Ngala :) I've googled but not found much in oz

Anyone else? :dunno:

I don't think you can, i've never seen them anyways but you might be able to buy them from America.

They've been out in Australia for a few years because I used them to predicit when I was ovulating for my last two children. They are really good because you get a smiley face when you are ovulating and a "o" (so blank circle) when your not. I found them way easier than interpretting the lines on regular opk's. They are really expensive though and you cant buy any replacement/refill sticks which is annoying. I used to buy mine from the chemist or places like Priceline.
