ONEVER Solar Mole Repellent, 4 Pack Ultrasonic Solar Power Animals Repeller Waterproof for Outdoor Garden Lawn Yard Get Rid of Moles Voles Gophers Rats Rodents

Every year for the last five I've had mole and vole infestations which isn't surprising given my garden backs onto farmland. Every year I get at least 20 to 30 mole hills over the summer months and several trenches made by the voles which, whilst not so visible, are actually far more destructive to the lawn.Despite the not so good reviews I thought I'd give these a go for the price and placed them around the circumference of the lawn nearest the field. Well, been about six weeks now and through rain and shine all four are still operating and NO vermin for the first summer in five! :-)There are some reviews saying these probably don't work and whilst I can't say for sure they do it would be some coincidence. But if this performance continues I'll be buying loads more for when these do fail.There are reviews saying these break easily and I can see why as they are very cheaply made (I pulled the top off one trying to remove it from the ground but poked all the wires back in and all good again). However, I wonder what people expect for these prices? Quality control? High precision? IP certified rating? They aren't going to be made under strict control and test situations in a factory are they - they are clearly put together in someone's living room which means they need to be looked after and brought under cover when the weather gets really bad. Despite the cheap components they don't seem to need direct sunlight for long periods to keep the battery charged.There are other reviews saying they are noisy. Well yeah, noise is normally a byproduct of vibration and it is that vibration that keeps the pests at bay. My advice is to insert them to the hilt which reduces the noise significantly with most of it dissipating under ground which is ideal.So really pleased with these and hope this continues.

I was a bit dubious of this product but after planting traps and getting poor results and my large garden getting destroyed by large mole hills I resorted to these repellents. Within 24 hours I went from 8 moles his to 4, then within 48hrs 4 to 2 and by moving these poles around the garden into the infected areas 72 hours later no mole hills and none reappearing! So far, so good ... Very Happy!

This product is truly awful. When thy arrived 3 of the repellents switched on and 1 appeared to have a faulty switch. They make an awful, loud beeping noise every 30 seconds which is terrible when you are sitting in the garden, as the 3 that were working were not in sync, so almost all the time there was a high pitched noise coming from somewhere. Not only that, but they didn't repel the moles, in fact, the activity increased. The moles even dug up the repellent when it was switched on and it ended up on the top of the mole hill.I attempted to contact the seller through Amazon, where I was told I would have a response within 48 hours but after a week I've still heard nothing. I will be returning them - my advice would be don't bother with these (unless I was really unlucky and had a faulty set, but I wouldn't know, as there were no instructions and the seller didn't come back to me)

I followed the instructions at first, putting them away from the molehills but that didn't do anything. Then whenever I saw a new molehill I put one into the hill and continued this whenever I saw a new one. Over the next few days the moles starting moving away and eventually they left completely. This is the first product I've used that actually worked although I had to find my own way of doing it.They are quite sturdy and being solar powered you don't have to spend a fortune on batteries.Hope this helps.

Very easy to use, obvious beeping from the 4 probes but very difficult to assess their effectiveness. After 4 weeks there is definitely less activity but there still seems to be a presence. If no evidence in another couple of weeks shall consider them successful.
