Review on WIEZ Wireless Reflective Waterproof Adjustable by Jenna Davis

I have had this invisible fence for a week now. What I love about it is that we live on a farm that spans many acres. I wanted my dog to be able to run and explore over 1/2-3/4 acres. The range is large. I set it to 90 meters (300 feet). He pages her as she walks behind the garage for losing contact with the collar, but the trees don't seem to be interfering with the connection. I can let her explore, but don't stray too far from home. Now she's always in my eyes. She was quick to pick up on sounds and vibrations and was rarely shocked unless determined (hunting deer or squirrels). If anything changes I will add an update but for now I am so glad I made the purchase.
