Anyone know anything about Lady Comp??

I use NFP but after a recent pregnancy scare, I want to step it up a notch. Does anyone know anything about Lady Comp or know about accuracy? It is fairly expensive so I would love to know its accuracy to the best that I can before I purchase it.

Thank you~ LadyComp Fertility Computer-Reliable and Natural Method for Planning and Preventing Pregnancy.

I have used it for a couple years successfully. There are a few things I am not crazy about. It gives me "red" days about 10-12 days a month and I have very consistent cycles. Also, You only have a three hour window from when you took your temp the previous night before it won't take your temp the following night. This has been a problem more than once with taking care of kids during the night. Other than that though it takes the guesswork out and I did like that.

Thank you! It is nice to hear from someone who has been using it!
