PetSafe Pawz Away Indoor Wireless Pet Barrier, Electric Training System for Dogs & Cats with Receiver Collar

UPDATE: collar just randomly stopped working after 2.5 months. My dog wears it pretty much nonstop during the day, but she is not rough on it at all, the receiver still looks brand new, Still... it's annoying that a product as expensive as this wouldn't work for long. I contacted pet safe via phone (their website says they have a customer chat but I couldn't find any link to do that) they called me back within 10 minutes and the customer service rep was insanely helpful and friendly and sent me out a replacement collar no problem. I just had to have proof of my Amazon invoice and it falls under their 1 year warranty. Hoping this one works longer than the first one!WHERE HAS THIS BEEN MY WHOLE LIFE?? First, a little background: I am an experienced dog owner, I used to train dogs in college and I have owned 2 labs of my own (both very well behaved) before getting my food obsessed yellow lab who is now 7 yrs old. The last 7 years this dog has tested my patience to the max. She is a high drive, "working" lab who once ate through a Chewy box to get at her bag of food and ate 9lbs of dog food without us knowing (that was a trip to the ER vet and a story for another time). I have tried EVERYTHING to get her to stop stealing food from the counters/table, but she still thinks my kid's food is an all you can eat buffet. Finally my mom mentioned this little indoor pet barrier and after reading up on the several options out there, I went with pet safe for a couple of reasons:1. I've had a pet safe wireless fence system for 10+ years and it still works. Hopefully this is just as durable.2. This is battery powered with replaceable batteries so you can literally put it anywhere in your house, unlike some that need a plug.My dog is already trained to an e-collar and a wireless fence so she is very familiar with the "beep" and knows to back off. I put this collar on and turned the barrier on, and the results were IMMEDIATE. As suspected she went right for the piece of jerky I put on the table. She got the beep and then a shock and off she ran out of the kitchen. She now sits outside of the kitchen looking sad and dejected trying to convince you she is starving. We have left all kinds of food out to test her and nothing has been touched in 4 days.-Be aware that if your dog is not familiar with an e-collar they will likely need a little more training.-The level of shock can not be adjusted, it appears to be sufficient for my 60lb, VERY persistent lab, however if you have a super stubborn dog, or very sensitive dog, this may not be great for you (although I think it's worth a try!)- you will likely need to buy a couple of other bases if you have a weird shaped room/large area to cover. For instance, I want to keep my dog off the counter and the table. If the base is on the table, the 6ft radius doesn't quite make it to all of my counters, and vice versa. For now she's terrified enough of the beep that she stays out, but I may need to get another mini barrier for the table in the future.-I think the price is a bit expensive for what it is. The collar strap is cheap (I compared it to my OG pet safe fence collar and the quality is lacking). I can stomach paying $75 for the collar and barrier system, but I wish the add on barriers were less money. That being said.... if you're desperate like me, it's worth it.- this isn't really training her to not take food, which I don't love because I believe in correcting the problem in your training instead of putting a bandaid on it (I'm sure the second the collar is off she will take full advantage and go right back to stealing), so I intend to do some training with her on top of the barrier, but at least this can keep her from self rewarding when she steals food. Overall I'm so happy I came across this and as long as it continues to work without issue, it's a home run!

Update: I had the device set at its highest (12 foot) setting and placed in a 2.5 foot doorway at the end of a long, narrow hall. After 2 successful weeks, my cat walked right past this device, went through the dog door, and got torn up my another cat. This unreliable POS cost me an ER visit, a huge vet bill, and almost cost my cat an eye! At the vet, I was further horrified to find that the heavy collar had rubbed the hair off my cat's neck, and it was starting to weep and bleed at the top. The collar had been removed every evening, except for the roughly 24 hours he snuck out, and was tight enough to zap him a few times when I watched him "test it" earlier in the week. The batteries are still good, so either my cat ignored the zap long enough to stroll 12 feet past the transmitter, or it is NOT functioning consistently and reliably.The fact is, my cat is a 100% indoor cat and has been his whole life. When he HAS snuck out of the house in the past, he has never stayed out for more than a few minutes, and he doesn't go very far. This time, he was gone for about 24 hours, which makes me think that the collar might have actually kept him from COMING BACK INSIDE. He got past the transmitter once, then wasn't able to come back in! And he's not really the type of cat to stand outside and howl for help, he would just sulk and hide, unless he's in pain, which is why I wasn't able to find him for 24 hours, until he finally heard my voice and crawled out from underneath the house all torn up, eye swollen shut and oozing, covered head-to-tail in blood."PetSafe" my ###.I should also add that I have experience with other electronic collars. I had never needed to use one before, until we adopted our recent pound puppy, a slightly-insane husky who streaked 1/2 a mile out of a fenced-in schoolyard AND across the four lane highway, because he thought the person calling him (ME) was one of the people standing over there. Since then, that shock collar has <literally> saved his life. That being said, this pathetic device would not work for most dogs. It is NOTHING like the device (in size, quality, or power) I trained our dog with. Maybe a small, timid dog, but I still doubt it.The collar is bulky and heavy for small animals. The shock is minimal. The beep it makes is pathetic and useless, almost inaudible, and there's no loud warning tone well in advance of a shock... which I've found to be VITAL when using these types of products. The beep should do all the work. They can get used to the shock or find a way around it, but the warning beep and anticipation of shock is worse, and ultimately what discourages them.This device might keep a timid dog out of a garbage can. Maybe. But DON'T COUNT ON IT KEEPING YOUR PET SAFE.
