My wife bought this for me for our anniversary and I've put it together and used it to wash an engine and engine bay on a truck and part of my driveway and so far it seems great
I just received my ePX3500 and have yet to put it to a test. My first impression is ir is sturdy, light weight and suitable for my needs. It met my budget and I'm optimistic it will out perform my expectations. It assembled easily, is compact and a good value.
