Pre-seed

Does anyone swear by or had any luck with Pre-seed? My husband and I are TTC our second child. We have a 3 1/2 year old little girl, and would love to have another baby. I started my period yesterday and we plan to start trying once it's over. I should be at my peak (according to glow) on the 13th of February, and I was curious about Pre-seed. I work at Target and I see it every day, but I haven't known anyone that has used it (that I know of). With our first, it kind of just happened. We were both 22 and just randomly decided we wanted a baby. Started actively trying the end of August 2013, and by October 31st, I was 9 weeks pregnant. I have a box of First Response ovulation tests (that comes with one pregnancy test), so I plan to use those soon when we start trying.
