Review on 🐶 WIEZ Wireless Dog Fence with GPS - Electric Pet Containment System, Range 98-3380 ft, Adjustable Warning Strength, Rechargeable - Harmless and Suitable for Medium to Large Dogs by Nate Caldwell

Don't let the 98 foot minimum height fool you. This is a 98 foot 5 inch (30 meter) radius. So if you don't have room for a circle nearly 200 feet in diameter, this isn't for you! I wouldn't have been able to use that if it wasn't for a neighbor who wanted my dog to be able to play outside with his dog. The device on the collar is also quite large and probably not suitable for small dogs. The battery life is about 1 day! 🙁 Every time you turn it on or the battery runs out, you have to reset the midpoint! 🙁 Update: This company did a great job of helping me with my issues. This is a great company to contend with. So if you decide this type of product is right for you, you can't go wrong buying from this company!
