Really don't think these work and there is no way to tell. The directions don't tell you much I don't understand why they have to be charged if they are solar powered.

The low voltage animal repeller lights were easy to assemble and work wonderfully. The green color blends very well with the surrounding greenery. We got these to use in our raised bed garden and have not had any trouble with deer or other animals.

[Edited a few weeks later] rabbits and deer don’t care about these repellers. I managed to take a proof picture. That bunny couldn’t care less about the high pitch sound. ———— I installed them a week or so ago, and so far I haven’t seen any rabbits around. Too early to tell for sure. The white switch is very flimsy - it broke off on one of the poles while I was setting it up. I could not find the missing piece in the dirt, but I know it’s on, so I am using it as is.

While these lights add ambiance to the flower gardens, Im not convinced that they deter animals. I have woods behind my house. Deer like to come munch on my roses other vegetation. I use a variety of deterrents including these. The lights have 2 settings. Its recommended that you change the setting periodically so that the animals dont get used to the sound frequency. Way too much trouble in my opinion. Also, some of the lights seem to automatically come on at dusk stay on, while others require motion only stay on for a short time. They are easily assembled the flame lighting effect does look nice. Ive had no issues with maintaining the charge. Once charged, the sun keeps them going.

The set of four were very easy to assemble. Shines brightly and looks nice after hours. Motion activated. You can hear buzzing whenever it’s emitting the solar sound to deter pests. I have placed them in my raised beds.
