I was really excited to start using the monitor and eagerly awaited my egg each month, BUT I'm not sure I would recommend it.
Cost for Monitor: $115 (ebay)
Cost for 90 test sticks: $150 (wow...never added that one up before!)
Overall Grade: B-
I did get a peak each month, but after I started charting I began to think the reading might not be occurring at the right time. I trusted the "video game" as DH calls it so much, that we only did our business when it told us to. If it was wrong, we were not giving ourselves a proper chance.
But the worst part was peeing on a stick each morning. I have longer cycles (average 33, max 40) so I had to POAS for like 15 days in a row. That means not peeing in the middle of the night, POAS when half-awake in the morning. Oh and it takes about 5 minutes for the machine to read the stick and if you don't take it out right away then you often get a mis-read.
I quit using it after about 5 or 6 months. Apparently, $250 later...oh well, this kid will be worth the money : )
