Lab Lover 5 out of 5 09.23.2016 at 4:57 pm I got this device for my 8 month old lab that gets into the litter box, gets on my bed, and worst of all open (yes opens) our kitchen cabinet that has our trash cans and drags out the trash. It was very easy to download the app and add the Delta Smart. You even identify your dog, you can take a picture of them so not only does their name, but their picture is on your phone screen so you are sure to be training the right dog. The smart tags were easy to add to the app. It was super easy to adjust the distance on the Tag too. I took the Smart and held it in my hand (not the shock side) to see how close the dog could get without/with the collar going off, and an easy up and down adjustment to set the distance. The battery cap is a little difficult to open so I used a flat head screw driver to help open/close it. The only down fall is that you have to wait for the app to open if you don’t have it open to use the training feature; other than that I love it! It is super easy to use. Highly Recommend.
