If one is considering buying one of these, please reconsider.
It is a Box, literally. No more, no less. A flexible plastic box that one can put a machine into. One could buy a picnic kooler, such as the Igloo brand, and have a $$ saving, plus a more sturdy container. I advise AVOID this product. One cannot lock down the machine (mine is an XR7700), so it is subject to rocking about. A kooler with two sheets of captive air (bubble wrap) placed inside will do more to protect your machine and cheaper at that.
