What are your thoughts on the Ava Bracelet?

Amanda

We've been ttc #2 for 4 months which I know isn't a long time (it took 7 months for our DS) but we got pregnant our first month and it ended with a mc so I think I'm more on edge now than I would have been. It's expensive but would make life a lot easier without having to do opks and I think is more reliable and accurate. Do any of you have the bracelet? Did it work? And how long did it take you to conceive on it?

I should note that I don't have any infertility conditions, but my cycles vary from 23-32 days.
