Ovusense? any good?

I've seen a lot of adverts for the fertility monitor ovusense, priced at around 295 UK pounds or 450 U.S. dollars. You wear something similar to a tampon overnight then it downloads the data and tells you when u ovulate, many girls with pcos have said it was perfect for them. Should I get this? it seems expensive and I start monitored clomid soon, but if this has worked for any of u, or not... I'd like to know! thanks!!
