The Ava bracelet

Hello!

I’m wondering if anyone has used the Ava bracelet when TTC? I’m considering purchasing it instead of buying opk’s as I feel like just throwing it on at nighttime would be easier? Does anyone know if it would be accurate in ovulation prediction?

I would just buy opk’s but I’ve heard that they can be inaccurate because if you don’t test at the right time, it could completely miss your hormone surge that tells you when you’re at your peak.

If anyone has any experience or knowledge on that I would appreciate it so much!!
