We live on a 16 acre farm with pastures, a wooded area and lots of cows and wild critters all around. We are remodeling and had to take some of our fences down so the property is not fully fenced. We like this product a lot and it has many features that we enjoy, plus a few that we don't. I recognize that this is intended more for hunting dogs and similar uses, so we are not necessarily using as directed, but with a tad bit more flexibility or functionality this product could be perfect for folks like us.What we love:1) E-Fence Feature: The app has three different fence modes. Mobile Fence, Geo Fence and E-Fence. The product instructions don't clearly identify the difference between the three fence modes for some reason. I had to go to google to find out from somebody else. However, we use the E-Fence every day. Simply select E-Fence and you can use your finger on the map to draw the boundary for your fence. It's that simple. We drew a boundary around our property. When our dog gets close to the boundary I think he gets a vibration, then a zap. Now he knows to stop before he gets to the fence line or he'll get a surprise. On the plus side, the E-Fence boundary stays programmed into the app. On the negative side, I hate having to manually turn on the E-Fence feature every time I turn on the collar. Sometimes I forget and the dog has been found roaming in the neighbor's pasture a couple of times.2) Long range. I haven't tested the 2 mile limit but I still get great range and it covers my whole farm.3) Good batter life. The batteries last all day and part of the next day. Sometimes we forget to turn off the unit so I would say we probably get on average 24 hours of battery life on a charge.4) Love the map feature on the app. I can see where my dog is, get alerted when he is running and so forth.5) We love the fact that the collar has a light on it. When it's dark outside our dog is invisible without the collar on. It's nice to look out our door and see where he is at from a distance even without my phone in hand.Things we don't love:1) While the app is convenient when I'm setting everything up or want to look at the map, I hate that it is required for operation. The app drains my phone batter really quickly. If I close the app the remote control starts beeping incessantly. Honestly, once I set up the E-Fence I would prefer to close the app unless I'm actively tracking our dog.2) I hate that the E-Fence won't stay on if you turn the units off or close the app. It may not seem like a big deal, but it's tedious to remember to turn on the E-Fence and I sometimes forget. Also, my wife is not tech savvy and can't figure out how to use the app anyway (therefore it is only on my phone) making the whole thing useless if I'm not home.3) Frustrating that my phone and the app need to be within Bluetooth distance of the remote for the whole thing to work. This really needs a feature that allows the system to lock in the settings without the phone around. Like it or not, we use this as a tool to keep our dog from wandering off if we leave the farm to go grocery shopping or something. I can't leave my phone home just to keep the collar working.4) the E-Fence boundary is not super accurate. The map appears to use a Google Maps image (or some similar service). I can zoom in pretty good and set the boundary but in practice the boundaries are sometimes as much as 50 to 80 feet off of the fence lines even though the fence lines appear quite dead on in the app.Overall we really like the collar. It does it's job and we use it every day. I think it is well worth the money after considering several other products. While we don't use it strictly as intended, it suits our needs just fine. There are some things that I would recommend to the manufacturer though by way of improvement:1) As mentioned above, provide a feature that allows a user to lock in the settings so that the remote can function without being connected to the app.2) It's great that this unit identifies when a dog is running. Can you also add a feature to identify when he is digging? How about when he is barking? This is a training collar and it would be great if we could use it to train for those other things too.

Best E collar for the money. Great batetry life, range and response. App is a little confusing at fiirst, but once familiar, it super easy.

TLDR: it's pricey for 2 dogs, but it has excellent range and good precision on controls.I use it for two German Shorthairs to keep them on track on our beach adventures. One of my pups really wanted to invade people's space and poo bomb their yards. These collars put a stop to that. Definitely waterproof, my girl proves that every day.Has all the features one would expect in a top of the line e-collar. Beep, buzz, adjustable zap, waterproof, rugged, good battery life, excellent range (9 miles!).Also, although the smartphone connection thing takes getting used to, you end up with great stats and feedback. Today, I went 2.25 miles, my boy went 3.35 miles, and my girl went 3.5 miles. There are optional notifications for things like pointing and barking if your dogs are not in view.If you have lots of pups, this is way cool because you can track 20+ dogs at once (although cannot imagine working the interface with that many).As with all e-collars, zap is the last resort and rarely used.My only real complaints are with the smartphone interface:1- you have to switch back and forth between dogs to beep/buzz/zap. I compensate for this by a lot of hyper vigilance and assessment of upcoming temptations to have the proper dog already selected.2-the interface is kind of small for the pups so I have to be careful not to fat finger it and confuse the dogs.Obviously, training makes all of this better, but with smart dogs, they know when they're wearing the collar and when they aren't.

Overall experience is awesomeness, ease of use and can use my own cellphone or a non working

The collars itself work really well but for some reason the frequency they run on cause my cat to go feral. Every time they are turned on she will attack the dogs at the location of the collar and it is only when they are turned on. I don’t understand the why behind it but it is every single time they are used so it isn’t a coincidence at this point. All in all, if you don’t have cats I see this being great but if you do then please exercise caution and be observant.

day one of using this. My doggo isn’t trained on the alerts yet so I am using the Geo Fence mode and just tracking her. No cell signal where I live so this is awesome. The interface is robust (and a tad overwhelming at first so don’t get discouraged). I love the options for training and tracking. I have found the tracking to be very precise and accurate. Very pleased!

I’ve used numerous Dogtra brand e-collars for training and have always sworn by them. This one was great, until we noticed a major design flaw. The button gets stuck/pushed it so you have to be careful. As a result of that, it will light the dog up being that it sends the stimulation continuously which could seriously hurt your dog. It looks like they have come out with a new model and redesigned the remote. Unfortunately I can’t swing another 400+ since I just bought this one in September of 23’.
