MorTime Set of 8 Solar Powered Mole Deterrent Spikes Outdoor Yard Gopher Vole Deterrent Ultrasonic Groundhog Stake for Lawn Garden

Great value for the price. Was not sure of how much distance between placement of each sensor so I purchased enough to place them approximately 10 feet apart. I had a terrible mole problem with holes and mounds throughout my yard. Information stated that you may continue to have problem for a month. I noticed my problem was gone in 5 days. Product is GREAT!!! Only negative thing is the sensor produces a beep that you will hear when you are in the yard, but I rather have the beeps than the moles. You definitely know its working.

Got this to help send the voles in my backyard scampering to a different location. Other than having to put up with the vibration sound, which you get with all of these types of devices, they have helped send those voles back into the nature area behind my house.Only issue I have is after a couple of weeks 2 of the 6 devices I got have stopped working so I no longer have full coverage and I am sure they will eventually try to move back in that area.

I ordered these because I have moles that are tearing up my beautiful lawn. I bought two sets and put them all around the yard where they were and they really seem to be working, no new damage. I can hear the noise they make when I am out there and they vibrate too confusing and irritating the moles till they go away.

Not too sturdy, tough to get in the ground and o e of the units did not work

UPDATE: These are a joke. We put them in and thought they might be working. It was weird because they are supposed to be ultrasonic. Meaning we can't hear the noise they admit. So not true. They beep loud and vibrate weakly. So I figured we could over look the noise if they were effective. I put them at our garden they claimed they could do it every 7,000 square feet. Which seemed quite a bit so I did place them a little closer and within a week we had to go forget one of our tomato plants and the steak was an even a few yards from it. So I put a steak right in between our three lasting tomato plants and for a couple weeks it was good until last night when a gopher totally annihilated our plant and there was a big old gopher hole right next to the steak. Not to mention we actually bought him for snakes and we've killed three rattlesnakes in the vicinity of these stakes sense. Bothers me is we are concerned for the safety and livelihood of our pets which are like our children and also ourselves so when somebody sells me a product that does not actually do what it says I take it very seriously seeing that it's about a safety issue with the people and the little lives that I love.We just got these in the ground 2 days ago so I'm not exactly sure yet if they work. However the first thing I noticed when I turn them on as they make quite a loud noise every few seconds they beat and vibrate. Even once they're in the ground they're quite loud however I feel that if they are effective that we can get past the noise. You get kind of used to it after a while and don't notice it as much so as long as it keeps the Gophers of snakes away then we'll be happy. If it turns out they work I will come back and update this review with a better rating.

Easy to use, but quit working after two years. Expected more from the product for the price.

Besides the one defective unit I'm hoping the seller will replace, There is one catch. You're supposed to mount the unit to a metal spike and then put it in the ground. I have an old battery operated unit (different brand) I've used for 10+ yrs that still works. I thought you would just stick these in the ground like my old one. What I did instead was attach them to T-Posts on a cattle panel fence that the bottom is in the ground. It's a pretty good effect and the vibrations travel further. If I get a replacement, I'd have to change this to 5 stars. They are small units but if properly installed should work well.

They really work well to deter moles in our yard. It's great to have something that works without poisoning or harming the moles. Highly recommended.
