Top quality product which has worked flawlessly since I got it.  I do want to clarify that the photo of the item is that of the 25 model and not 35.  The 35 model has a rounded "spoon" style pivoting mechanism vs the square top, bottom, sides style seen in the photo.  Other than that the OEM plastic bag wrapper for the item was dirty, little tattered, and some areas of the printing were worn away even though the bag hadn't been opened.  Copyright date on the bag was 2007 so I'm guessing the item may have been in a bin for some time; but I've usually found older products to have been better made than newer ones.  One other note: I also have some of the plastic construction impact sprinklers from Rainbird and thought it was odd they seemed to work really fast.  This model and the 25 version are the slower operating ones you often see used in orchards and vineyards.  Evidently the plastic versions, with their lighter mass, just react a lot faster.  So, if you like the slow, very pleasing, lazy day sound you'll want the metal impact sprinklers.  I wouldn't hesitate a minute to buy another one of these.
