I really like mine. The tension is adjustable so you get the bobbin wound properly..they don't adjust automatically!! The less expensive model that's been available for several years doesn't fit all bobbins, I know the Pfaff vision ones don't work with it, but I thought the new "improved" (more expensive!!) version was revised to accept the bobbins the old model wouldn't. Don't know for sure though. Since I take my machine with me to classes or mystery get togethers, I like to take many prewound bobbins with me so I don't waste time I've paid for to wind bobbins!! When I think of all the gadgets I've wasted money on..well at least this is something I still use
