These are easy to use and worked for our mole I blew in the garden. Great costumer service!!! Make sure to follow the instructions and charge the solar part for 48 hours before using. So far so good!!!!

We have been using these devices in our yard for a couple weeks and the results are AWESOME. Since we have a dogs, we didn’t want to use any poison or chemicals in our property that could be harmful for them, it looks like we found the perfect solution with this product!The devices are very simple to install and they charge very fast with the sunlight, the materials are excellent and seems very durable.So far we are very satisfied with the results, no more mole hills in our garden :) highly recommended!!!

We actually bought this to try to keep snakes away. They are really bad in our neighborhood this year. Someone on the FAQ section asked if it repelled snakes and the answer was yes, so we figured we would give it a try. Everything came on time and as expected and they seem to be working great. We haven't seen any snakes or any other unwanted visitors!

Got this mole chasers to get rid of the pest that were coming from my neighbor garden. As soon as I opened the box I knew that they were going to work fine, the quality is great compared to a similar product we had and the solar panels are big enough to charge the devices quickly.They produce a sound every 15-20 seconds, honestly I thought that I wouldn’t perceive the sound but you certainly can hear it.They were fully charged and functional after a couple hours placed under sunlight, the first days I was very skeptical but after about 10 days the results exceeded my expectations, the moles were gone !!!!!! I’m extremely grateful that I found this product, THANK YOU!

These did repel voles that were eating the roots to my tomato and bean plants. The only problem is that by the end of the growing season, two of them would not stop the sound and would go until sundown. Not the timed pulses of sound they were supposed to emit. The other two did continue all through the winter but are now barely emitting any sound, when originally they were strong enough to hear from more than 10 to 20 ft away. I'll buy some others and try them, because this type of repellent device did repel voles in my case.

Purchased to help with a mole problem after a vacant lot began development nearby. I found instructions a little vague, I would have liked to see an infographic explaining how / why it works. Installation was fairly quick and easy, I wish the solar panels locked to the spikes more securely.After installing them I noticed one of the four wasn’t working, I moved it around the yard to see if it wasn’t getting enough light; didn’t work. At this point I’d missed the brief return date. Seven weeks in a second one stoped working completely, and just last week the third one is now just steadily buzzing instead of pulsing intermittently. So only one of the 4 is how working properly.I wouldn’t recommend this brand, the 4 units that came with this pack should have been more than sufficient for the square footage in my back yard and the moles are still winning.

This Ultra Wave really ticked off some moles. When I first put it in the ground, they made runways like crazy. One runway was 20 feet long before the mole decided to surface and beat buns away from the noise. He left behind a hill a foot tall. A few others moved off into the forest without coming up. I love it, I haven't had runways or hills in a week. There is a buzzing noise when close to the Ultra Wave, but I can't hear it inside the house. And if it gets rid of the moles that quickly, I'll listen to a little buzz.

I have been using them for 4 weeks, the solar panels work great they charge extremely fast and work for several hours. You actually will see the number of mole holes reduced when the weeks pass, at this point my property is completely free of them. Very happy with the results !
