INVIROX Dog Shock Collars [Ultra K9 X2] 124 Training Levels, 4 Powerful Modes with Night-Light and ¾ Mile Range 100% Safe Dog Training Collar System for Large Dogs IP67 Waterproof (Black)

I appreciate the battery life, the buckle style, rubber collars, and definitely the night mode/light! I really like the fact that the beep is loud enough that I can hear my dog from a distance!*** The only thing I would recommend for the future, is to put the vibration and shock on one side and the beep on the other. But I suppose that’s personal preference, also if you’re coming from their previous collar that you are familiar with its hard to retrain your brain in an immediate need situation.Personally, I think it would be really amazing to have separate shock buttons for each collar so you don’t have to look down and memorize or confirm which one ur on

These are great collars just the dogs are rough on collars and got the old ones wet too much and they stopped working, but other than that they are easy to use.

Love these collars! Both my dogs wear them daily. If you follow the instructions and be sure not to traumatize them, they will thrive! My dogs don’t need leases anymore and when I whistle they come running. I’ve never had to do more than vibrate their collars. I would definitely recommend if training stubborn dogs.

Everything is great EXCEPT the handheld remote.Needs a slide from dog 1 to dog 2. Push button doesn’t allow for blind toggling in pocket.

Purchased after my mom getting one. Works perfect. Range is pretty good. You can adjust settings easily. The battery lasts a long time!

Everything works good but when the dogs get like a hundred yards or more it doesn’t really work that well maybe it’s the interference with the trees but it definitely isn’t a quarter mile long

For this price range, these are the best training collars I have found, yet. Over the years, I’ve tried a half a dozen different ones. These have great features, the longest range, and the best battery life by far.

One of the best collars i bought i tried many other top brands like sport dog Garmin this product can't is a million time better and more versatile like battery life easier to use and love the light on it the range on this product is outstanding had the collar for about a month so far my dogs responded to the beeping and vibrating so we'll I haven't had to use the shocking feature yet would and have recommend to anyone
