Very cheap processed, but not expected at the price so different. Beeps every 30 seconds but quietly audibly when you are staying in a quiet area near it very annoying -. This is true but fortunately also for moles to. Although by no more than 20 m as in the product description, but at least our mole for a few days now holds 5-7m distance. Enough for me. We'll see if that works permanently ...
Update and reduction to a star: Unfortunately, this does not permanently. The mole is back, the last hill was right on the mole fright. Therefore, unfortunately, my new Conclusion: Disabled. And the neighbor complained because he at night can not sleep with the window open ... him annoying beeping probably more than the mole ...
