i have angelsounds, its great, well now im 12weeks at least. I wouldnt reccomend using it before as it'l worry the hell out of you. Its good tho, altho use ur own head phones as the ones that come with it are crap. use LOAds of gel. I kept my legs flat and have to put doppler right down low and slowly slide from side to side to try find it. It gets easier when you know what your looking for (maybe look up heart beat on youtube) we did and it helped as theres loads of different noises going on. Theses days i can hear baby moving too, its sooo exciting!! good luck. XX
