Summary: Three month supply?? NOT!
Comment: If you have a long cycle, expect to use 20 sticks that first month since the machine starts you testing on day six and if you have not peaked by day fifteen it will ask you to test clear past your peak day and all the way to day twenty-five. Lesson learned after I had to buy another box of sticks to finish out month two when it started me testing on day eight. I think next month I will just time it so I only have to use half a box per cycle (15 sticks). Just start testing a few days later than the machine tells me to and stop testing after peak day will certainly cut down on stick usage and cost.
Cons -- After you have spent morning after morning looking at the lines on the stick and seeing which one(s) show, it is easy to predict what the machine is going to say. I sort of feel ripped off by having to use the machine to tell me what I can plainly see with my own eyes. But the machine makes it easy to keep track of cycle days and it is an easy reminder to test, so I am not overly upset.
I also find it easier and more accurate to use the "dip in a cup" method over the "running stream" method. Just use a disposable Dixie cup - much less messy and splashy.
I am not sorry I bought the system -- I just need to tweak it a bit so that the sticks actually last me for three months. Gave it four stars because it DOES what it is supposed to do, took away one star because it gets expensive to use as directed if you have any issues at all with your cycle.
My suggestion is to not rely too heavily on this machine and take the time to learn your body signs since sometimes signs come later in the day, even when you have had a low fertility reading in the morning. This is only an additional tool in natural family planning.
