Lets face it, these are cheap.  Pros: low price, soft brushed finish & curved back detail, very light, reasonably sturdy, clean lines, cushioned seat.  Cons: vinyl seat is very shiny & looks like (you guessed it)  vinyl, welds not super clean, a little wonky but easily adjusted.  These are probably not your dream stools but could be a good interim solution. 
The excessive wrapping is just silly.  I used a sharp, small nail scissors to remove it, being careful not to scratch it & it took me about 10 mins per stool to unwrap.  5 minutes to screw on seats.
