I bought an OV-4 the end of January (1/31/07).. (from The Vermont Country Store) .. I misplaced my registration card and just noticed that it's too late to register it.
But I wanted to be sure to tell you that I find it to be an amazing, wonderful little machine. I have tried many and searched for a long time for a 'real' vacuum cleaner ... one of quality, that is very powerful and easy to move around with, with useful attachments and a long hose, plus this one is even small and light-weight. Also, I was pleasantly surprised that the tiny little filter bag lasts longer than I expected; the contents appear to get very compressed. This fine tool will be a part of my household for a long time.
