As far as I know, there is only one brand of esturus alert patches. I get mine from my Genex rep but I have seen them in several catalogs. Just make sure you don't get Kamars.
We use estrotects.
www.estrotect.com PLUS if its your FIRST time ordering from them, just click TRY ESTROTECT, and they send you a package of FREE ESTROTECTS!!!!!. It was awesome, they sent us like ten for free, so we were set for the first breeding season, and they worked GREAT!!!!!
DO NOT USE KAMARS. Its a little hard to tell when they've been ridden, BUT when you pull them OFF, you pull EVERYTHING!!!!! IF YOU CAN EVEN GET THEM OFF. We just had a really bad experiecence with them we tried them.
