F810 Wireless Dog Fence

Set the radius to just shy of an acre and my lab hasn't wandered past the line once in three weeks. The collar fits his 22-inch neck with room to spare, and the battery still shows charge after a full day outside. Genuinely surprised how quickly he picked up the boundary.

I was nervous about the waterproofing since my lab jumps in the pond daily, but the IPX7 rating holds up fine after a month. The collar fits his 22-inch neck with room to spare, and the circular boundary keeps him off the road without any buried wire.

The adjustable radius is the feature that sold me, I've got it set to about 200 yards and my lab stays put even when the neighbor's dog is out. Battery easily lasts a full day outside, and the collar survived a pond swim with no issues. Setup took maybe 20 minutes, way easier than burying wire.
