Pros: Looks very well built, the plastic quality is good, battery compartment has rubber seal to provent water leak, so suitable for outdoor usage. The solar charges enough power to operate the device.Cons: Although, the device is running no problem, it does not work for pest repellance at all. I put is one feet under the tomato plant, the fruit was eaten the third day it was installed by chickmuk. Ok thinking maybe the tomoro is too delicious to resist for them. Move this near some plain plants, the next day, three plants were eaten to the root. Looks like it attract the animal come to here?
