The voice of buyer: I have a spot that I need to keep the dogs out of. This works great for that. It's easy to set up, and it's easy to train the dog to the beep. One thing to note is that you can't turn off the shock option on the boundary. It will shock only, not just beep. I could see this being really great as a boundary if you have a camper or if you go tent camping and need to keep your dogs in a single area； Upgraded Wireless Dog Fence w/ Charging Station Upgraded GPS Wireless Dog Fence 2023 New Mode Wireless Dog Fence 2023 New Mode Wireless Dog Fence 2023 New Mode Wireless Dog Fence Add to Cart Buying Options Add to Cart Add to Cart Buying Options Customer Reviews 1.8 out of 5 stars 7 2.7 out of 5 stars 3 2.4 out of 5 stars 24 2.8 out of 5 stars 26 2.8 out of 5 stars 26 Price $119.99$119.99 — no data $68.90$68.90 $109.99$109.99 — no data Best Use Environment Whether you need it indoors or outdoors, the wireless fence performs effectively for homes with small or medium-sized yards, as well as in rural areas and wooded location Outdoors in open areas with a clear sky view for optimal GPS signal reception.
