I bought this product after a prolonged outage of EDF and to start finishing work in a house nearing completion. It ensures trouble-free relay for a freezer and fridge in case of power failure and the basic tools (drill, sander, paint gun, ...) when working. The protections are reassuring (circuit breaker, oil level warning low, ...) and it is one of the few in this price range that offers 3 doses. Of course it is new but the boot is easy. For noise, this is the equivalent of a mower when it is requested. I recommend this purchase.
