I am currently on my 4th KM2K in as many years and I really wouldn't want to be without it. However, there is a very serious design flaw at the hinge of the device. Every device I've had has broken at the hinge after not very long usage and certainly without any harsh handling. The little hinge just... breaks, usually when I am removing the springs for cleaning. It is very frustrating because it is not an inexpensive purchase. And it has happened repeatedly. I don't know if I'm ready to spend nearly $100.00 on a device that will only last little less than a year.
