Unlike others purchased elsewhere these come on and work.

These solar mole detectors didn’t last a good 2 weeks!!!!! First of all I let them charge up for 2 days by leaving them off and directly in the sun. Like you are supposed to do with MOST Solar items. I turned them on an immediately you can/could barely hear them vibrate.I figured they might just have to stay in to charge. Tried that and still you could barely hear them at all.Out of 10 that came in the pack, maybe 5 work now. Waste of time and money. I’m definitely will be looking for another company to buy them from.I wish Harbor Freight didn’t stop selling theirs because they were sturdy and lasted a long time.

Easy to use. So far no moles in the back yard. Seems they vacated. Very pleased!

Easy to install but have to place it on chargeunder the sun for full function, overall I guess it's slowly repelling the moles out of the yard.

I bought these because they said they were "Ultrasonic", which means they emit a sound above 20,000 Hz. At that frequency, humans cannot hear it. These devices emitted an annoying noise that I certainly COULD hear. It may drive away a pest, but they were driving ME crazy as well!

Waste of time & money. I installed these units as instructed and within a few days I had Gofers digging holes within a few inches of the units.

Solved all my Mole problems in garden

I would have returned these but you have to use them for a while to make sure they work. They did make the moles leave my yard but the function of the devices have all stopped working even though they're solar. I would not buy them again.
