Query: Buyer Beware

I received this sprinkler and it does not oscilate at all. I called Nelson direct and they do not think it is really one of their products because all their sprinklers have a flow control or a timer and this one does not have either. They have asked me to send it directly to them and they will send me a replacement and run the investigation. Buyer beware!
