The quality is great for the price I am very happy. There aren't any instructions or the assembly but you will figure it out. Be sure to check all of the packaging for loose bolts as I nearly through out a critical part.
Great microscope for the money. My only complaint so far is that I had to level the base because the bore isn't plumb. (one thin edge, one thick edge) The adjustment screws are a little short but it worked out OK. Quick shipping in western Europe too.
