The Beacon, great product!
This is the 3rd one that I own, Amber my pit-bull needs 2 cuz she has two different coats the 3rd is for Miss Dixie Belle my late wife's chihuahua mix . When they go out in the yard at night Ambers is flashing red and Dixies is flashing green which is a huge help as she is black almost blind and deaf so this way I know where she is where she is at night.
