The system was easy to install in my mobile home and work there properly. But the quality of the plastic material is absolute Far East cheap junk. The suction cup crumbled after a few days in the sun at the slightest tightening of the adjustment, the recording of the monitor blurted when slight tilting, which is often difficult to avoid when inserting the holder, also a bit away. Bin fortunately hobbyists who knows how to help himself. For everyone else, I recommend investing a few euros more and buy better quality! As impudence I felt that Walser Returns accepted only via DHL. I had overlooked that and sent the zebröselten suction holder by Hermes for a warranty claim. Walser refused to accept! Good service is different. Unfortunately, I had rated Walser immediately after receipt and control function of the device as far too well, but now turned out to be wrong. Before I now again 4.90 euros for postage dispensing, which exceeds the value of the suction holder many times, I have bought a better suction holder (Hama) at Media Markt.
