Ovulation tests

Sarah
I have been reading up on ovulation tests and when is the best time to take them and how long and how often. I of course have read conflicting results, so I am turning to all of you for advice! Some say between 11-3 is the best time and others say 12-8. Some research says twice a day 10 hours apart? Do you test every day when you are ovulating? Help me!! 
Thanks,
