marumatu 5 I ordered Sumeber’s mole repellers on a friend’s testament of their effectiveness. When mine arrived, I misplaced the directions that came with my repellers and Sumeber CS immediately emailed me a new set. While assembling my repellers for solar charging, I noticed that one of the repeller’s solar battery switches was set to “on” and as it turned out, unlike the other two, was unable to hold a solar charge. I contacted Sumeber CS again, explained the situation and asked that the unchargeable one be replaced. Sumeber CS responded immediately in agreement to sending a replacement. Much too my surprise, Sumeber customer service emailed that they went ahead and shipped me a whole new set of 3 repellers. Thank YOU Sumeber. With 5 repellers, the moles in my garden will definitely be moving out.
