Every sewing machine needs a cover!  This cover is an update of the old ones.  The difference is that the old ones had a bottom that was connected to the machine.  Because of the nature of the design, you want to be able to completely remove the machine from the case.  It is a universal size.  I would have liked to see some protective material against the lower and sides of the case to protect the machine from sliding around or moving and/or a strap to secure it to the bottom as a back-up to the side locks.  It is entirely made of a plastic material.  The sale price made it worthwhile not to wait and this company sends them out immediately!  The side locks connecting the top to the bottom are very secure so the bottom will not fall out while you carry it.  The handle is smooth and easy to hold.  Go for it!

Pros: complete protection of sewing machine, east of use, price
Cons: added cost to machine purchase, no inner protection of machine
