Ray,
That's correct, problem is you can't check the ID plate until you unpack the compressor. Sellers have been known to say anything to make the sale and advertising pictures can't be trusted. At this point in the discussion, I'd mention seller, best-homepro, everything he shipped had such an ID plate, sadly he seems to be out of inventory. Most will now purchase from Walmart or Amazon and secure a warranty, different manufacturers listed on ID plates, not aware of any "YONGYIHENG" listings on these, but I might be wrong. Wish I could be more helpful, but members seem to enjoy success with Walmart and Amazon supplied compressors. WM
