This is a great deterrent! It’s nice to get rid of rodents in a humane way

Avoid buying these at all costs! They do not last at all. Haven't had mine long but now they're not charging anymore. And the battery is not user replaceable. So since it's past the time that I can return them, I'm stuck with them and they don't even work anymore.

The devices worked, it just took about three weeks. They won't work over night but they do eventually force the critters to go away.

Dose not work

By experience, my gardener claimed he can find the gopher tunnels so he installed the Solar Powered Gopher Repellent in the ground. The very next day a dirt mound was a few feet away. The following day, another dirt mound was found on the corner by the driveway. Still just a few feet away. It makes an annoying sound but doesn't seem to bother the gophers. The best way to get rid of them is the old fashioned traps placed in their tunnel. It kills one and just leave the trap in there so his buddies avoid the area. Temporary relief from them for at least a year. I was hoping for a more humane way of getting rid of them.

I had a gopher pulling my plants through raised garden beds and these have worked wonders! I have absolutely No activity in the area that I set up these stakes. You can hear them.

So so

I have to say they seemed to work for about a week or so. Gopher activity seemed to slow down but just went back to normal. Holes even opened up right next to them.
