I can’t tell you how grateful I am my hubby bought me this breeder alert last year! Makes foaling so much less stressful! I get to sleep, and not miss a foaling. Woke up this morning to the alarm about 1 a.m., just in time to go out and assist the mare! She had elbow lock, and we had to get that straightened out so she could pass the foal. We did 12 last year and will do 15 this year . I used to be so exhausted at the end of foaling season . Thanks for the great product
