Firlar 2 Pack New 2019 Upgraded Solar Mole Repellent for Snake Ultrasonic Vibrating Rodent Repeller Vole Chaser Pest Deterrent for Outdoor Lawn Garden Yards (Green)

I don’t want to blame the manufacturer for my problem. But be careful trying to move or just removing top for changing settings. It will come loose then you can rip all the wiring out when you pull up on it. I put one in but concerned that it wasn’t set the way I wanted, so I pulled on the top square and ripped the wires it that went in there. That was no big deal didn’t break it; just had to open it and reconnect. I think it was about to rain and didn’t want water to collect in the uncovered base stem with the vibrator and noise make in it. Pulled on that, it was two pieces. Ripped the wires again. I since soldered them together and it works. Good news is if they have been in ground for awhile, they come out easy. When first install put them in right so u don’t have to try and pull it right back up. Snakes need no sound. Mammal pest u use sound and vibration or just sound.

I REALLY WORKS ON THOSE PEST, THE SQURRELS ARE A BIT SMARTER THEY WILL PLAY BEHIND THE SOUND WAVESO YOU MAY NEED ONE IN FRONT AND ONE IN BACK

I have no more moles in my front yard they all moved to back now I have to buy more so they can move on.

So far so good. Easy to install

After a couple weeks in the ground they have stopped functioning no sound no vibration
