"I can't recommend the Lady Comp enough, it has been the most positive, empowering decision I've ever made. I've been using the Lady comp for 7 months now. I can say in 7 months it has been 100% effective also tells me within a day or two of my due menstruation date, which is brilliant. It's great to travel with as it comes with a cute, discreet stylish non-leather pouch. Absolutely A class product!"
