Review on 🐶 AngelaKerry Wireless Dog Fence System: GPS, Waterproof Collar & Remote for Dogs 15-120lbs - Ultimate Outdoor Pet Containment Solution (EF 851S) by Keith Mertz

2nd update on 2nd device (after the first update this morning). He stopped working altogether. I have no idea why. 3 days have passed since the return deadline. Let's see what the seller does with it. They responded to the problems we had with the first block (1st check of the 2nd block). 2nd block, there are no problems with moisture. We returned the first one with a refund and a $14 shipping refund. Consider this device for a second dog. I enjoy working outdoors with a dog nearby and don't have to constantly watch like I'm wearing a manual collar. (First block - there was moisture in the glass of the pad for two weeks. No rain just melting frost and dew. in the grass. The seller suggested we send it back to China at our expense for a replacement for $14. Well why should should I invest more money in something that shows signs of failure after only 3 weeks?I missed the return deadline by a few days,I would take it to our daughter as I thought it would dry out but it doesn't.seems good and I would buy it again for our situation if it was durable.Can't leave the dog with it,although left unattended it's not reliable enough not to electrocute him.there was a signal.must stick with it. it varies in range and for our p-targets, which were pretty close; it's not exactly like a labeled electric fence. You need to learn to respond to sound, not necessarily location.)
