Ava Bracelet

Has anyone tried the Ava Bracelet with success? My husband and I have been trying to conceive for 7 months now. I read Take Charge of Your Fertility, I use glow, my BMI is high but I’ve been working on that. I’ve trimmed caffeine to one glass a day, been trying to eat the foods that help fertility. I check my bbt every morning, etc... so I’d like to try the Ava Bracelet but it’s a little expensive if it doesn’t work. Any experience with the Ava Bracelet is welcome! TIA
