The quick connect/disconnect connector on the end of the sprayer wand disconnected from the stainless tube. (5 months old and used about 10 times.) Warranty replacement is not available, so they offered to replace the entire pressure washer. However, they will not send the unit until I send the existing unit back. I have no box for it, so I need to buy a box to have the warranty item replaced or wait an undetermined amount of time for the spray wand to become available. This item is still under the original warranty and I bought the extended warranty when I bought the pressure washer.
