This is a gently used fertility monitor that we used with our baby 19 months ago...it worked after only 2 months using this...obviously results may vary but I do believe in this monitor!

I have the book of instructions to use with it, but no box.  I put 4 new AAA batteries in it today so it's good to go!

You will need to buy the sticks to go with it as I have none left, but shop ebay for them as they are cheaper than the store i have found.
Keep in mind we bought this retail at over $130!!! 

Thanks for looking!

The Clearblue® Easy Fertility Monitor

The most advanced method to maximize your chances of getting pregnant. Our  Fertility Monitor  reliably indicates the days of your cycle when you are most likely to conceive – the days closest to when the egg is released from your ovary (ovulation). Most home ovulation and fertility tests identify the 2 best days to get pregnant during a woman's cycle by detecting the surge in luteinizing hormone (LH) that triggers ovulation. The Clearblue Easy Fertility Monitor not only shows these 2 Peak Fertility days, but also identifies additional fertile days when you can conceive (view our Understanding Your Ovulation & Menstrual Cycle demo). By detecting a rise in estrogen, The Clearblue Easy Fertility Monitor can inform most women of an extra 1 - 5 days of High Fertility prior to their Peak Fertility days. This means that you know all the days on which having intercourse is most likely to lead to conception.

More accurately identifies a greater number of fertile days than any other method. Typically identifies up to 6 fertile days each cycle. Is the only Monitor to detect two key fertility hormones. Stores your personal fertility information and displays your level of fertility every day. Is simple and easy to use. Is a 100% natural, non-invasive way to increase your chances of conceiving.
