The best thing I have bought for my Cattle Dog
I have a 2 year old Australian Cattle Dog who runs with me... A lot! She easily runs 70-100 miles a week. I bought this collar to keep her in control and focused while we are running. She is off leash 90% of the time during our runs (only on-leash when required, such as races or State Parks, etc.). The collar has been our number 1 training tool. I run with the remote in my hand and can easily get her to go where I want her to go. Verbal command has been a lot easier AFTER we got the collar, as we rarely have to correct now. I highly recommend the 425S.

Love it
We have a German Shorthaired Pointer when we first got her she wanted to eat our outdoor kittens (common for the dog we know) however we wanted to train her to leave the cats alone and she did wonderful Mind you she knew her commands and within 3 days time she knew NO and doesn't bother cats at all!!!
Mind you she loves to run and swim and when my step daughter lets her outside she thinks its time to run and find the pond next door So since we own over 10 acres and all our neighbor's have ponds we are going to invest into the 1 or 2 mile range one within time since we have been so pleased with this one it will also be great while in the field.

Great product and customer service!
I just recently bought my own home, and my stubborn Shepherd/Collie pup wouldn't listen to me once he was outside. After a few times of running over into the neighbors yard (not a friendly neighbor), I decided to give the e-collar a try after several of my friends recommended it. It works great. If he doesn't come when I call him, I only ever have to tone him once and he is listening to everything I say. I rarely ever have to use the stimulation button. Now that we have had the collar for a while, 75% of the time anymore I don't even have to tone him and he comes to me. He comes every where with me, and it really has been so useful and such a relief for me knowing that he can come along and behave while having fun at the same time. I've only had one problem with my collar and that was two weeks after I bought it from Field and Stream. Stimulation levels one and two weren't working anymore, and I didn't dare use the level three button when it wasn't necessary. I took the product back and customer service was very polite and helpful, giving me a brand new collar and remote and some useful tips on how to make the battery last as long as it can. Granted I did pay for a two year warrenty, I never expected that I would be given a brand new product. I'd recommend Sport Dog to any of my friends.
