I have yet to actually use this table.  I have to take a couple of links out of the chain as my Singer sits very low.  I agree that the cut-out for the sewing machine should be finished rather than raw edges to potentially catch on fabric - especially as I use finer fabrics in sewing clothing.  That's something I actually wrote to the company about.  It feels very stable, even on my carpeting and I definitely look forward to using it.  

Pros: Very easy to set up.  Simple table will fit in with almost any decor.  Sturdy even on my carpet.
Cons: Not very easy to raise the drop for a shorter machine.  Cut out needs to be finished rather than raw edges.
