Before I bought this product I had a more favorable Noname variant. Since the air pump at a Czech air lift in the living room is used and the Noname device was simply too loud (even when running television and turned up 5.1 system has always been to listen and very annoying a distinct hum!), I've bought the Eheim 3702010, since the other reviews were promising. At home I have arrived naturally first connected the Eheim air pump connected to the grid. At first I thought the pump had broken down ... Until I realized: the running anyway! And so quiet! Even at full power at the TLH it was barely audible (max. 1m distance, cocked listening) is running TV (even if that was turned down) nothing. I would buy this pump itself again and recommend to anyone who wants a quiet, powerful device.
