Best purchase ever

Tonight I used my doppler for the first time since I had the freakout last week. It literally took me less than a minute to find little peanut's heartbeat. I knew exactly where to look and I could hear it clear as can be.
It's amazing to me that such a cheap product could give me such peace of mind. I wasn't too worried this time around, but since I hadn't been feeling the little one move as much the last few days, I decided to check.
