I posted a few days ago about my new Yong Heng compressor and how the first thing I managed to do was to break the crankcase breather off. Well I was surprised today when I opened a package delivered from Amazon that I wasn't expecting and it was a package of 5 new breathers. I didn't order them and the package had a gift receipt in it. I can only assume that the seller I purchased the compressor from on Amazon saw my post here. So to them I say thank you and that's great customer service.
