Comments about SportDog SportDog SDR FS Add A Dog Collar:
First remote control was faulty. Company did a great job replacing in fast with one that works. Not sure if range of collars is quite what it advertises. But collars have been great. Used 3-4 times per week in the water and dogs have responded very well. Used primarily to encourage dogs to come when called. Used as a pseudo-electric fence when working with the dogs in the yard. Has worked really well for our purposes.
