This was a "big upgrade" from the Delta we had for 20 years (no issues, separate sprayer).  The Delta was leaking for years but just around the escutcheon so we lived with it.  This faucet is nice, but I had to call as the spray feature was showing up during solid stream use.  Especially noticeable and annoying when filling the tea kettle and spray all over the top of the kettle.  New spray head on the way.  They do stick by their guarantee!
