Ovulation testing

Kim
Hi ladies, 
What is your preferred method of ovulation testing? The cheap eBay strips or a brand name electronic tester? I think I missed ovulation this month as I only started testing towards the end of my green week in another app (start in this app) and it was never really dark (see below) and totally white today when Glow reckoned I should be ovulating. Clearly not....
I never needed to test with number 1, she happened while on holidays before official first month TTC, which is why I wasn't testing religiously, hubby thinks it will happen when it happens....
