Bought last week, assembled and tested today, so far I'm very satisfied with it's performance, can't comment on durability though, since it's only been used once. My only issue is that the very large GFCI power plug is too big to fit into regular household outdoor weather proof outlet box with cover.
I did enough research online to quickly discover that this unit (ePX3050) meets all my requirements as a homeowner with reliability and without the hassle of a gasoline engine. I bought it less than a month ago but I started on my projects immediately and have used it continuously for hours with no problems. The engineering behind this unit is impressive in every respect, from performance to construction, convenience, and even aesthetics. It's compact but not a lightweight, and it packs a punch. The fact that it's not top heavy (like so many other brands), has four casters, and can follow you around while you work without tipping over is a HUGE plus. As with any pressure washer I recommend the use of a water-supply hose with the capacity (5/8" dia. for example) to provide adequate water to the unit. Westinghouse has a real winner here, and it costs less than one would expect. It has more than met my expectations and I highly recommend it.
