With all of the Yong Hengs and Vevor compressors going crazy outrageous on price on Ebay, I decided its time to upgrade. I call Pyramyd Air and talked to a very nice lady named Ruth. She was very informative of the Air Venturi compressor and talked me into it. I figured I may need some customer service so I went with them. I can't wait to get it. It's the big 4500psi 110v. Any suggestions of what I need to do or look out for while using it?? I already got the oil coming for it Free.
