Review on Enhance Sewing Precision with Janome Ruffler for AcuFeed Models by Morgan Gilmore

You have to tighten the sewing needles in the machine with a screwdriver or the vibration of the winder will loosen the needle and, like me, you'll find more broken needles in an hour than you ever thought possible. Also make sure to align the position of the needle with the hole in the picker, otherwise the needles will break. Ruffler is great but expensive and noisy and there are no directions. I've used Ruffler on several brands of machines but they had considerably more instructions on all uses, the expensive Janome doesn't offer anything useful and for a new sewer it would be a deal breaker. Manufacturers sometimes assume that consumers know as much about their devices as the company does.
