Delivery was extremely fast. The table was very well packaged and fully assembled. The shelf is easy to adjust and not only does it hold my old machine, but it is a perfect fit for my Singer Quantum Stylist 9960. There is only a 1 inch opening on the end.  The opening is big enough even though the table measurements say otherwise. I am very pleased.  I got rid of the cabinet that came with my old machine when I moved 15 years ago and have never liked sewing at a desk or table, I know I will enjoy this and am eager to begin new projects.
