I was expecting the part that attaches the air tube to the tire that gets air fed because that's what my old tire had. The instructions that came with the compressor said it was there, but after looking at it, re-reading the box, I found that it didn't come with that part. Since my old man had one, and my limited knowledge of air compressors and tools in general, I assumed everyone had one. Because this part is not on the item, it is more difficult for me to use it. However, the compressor works, so I will not be returning it.
