My husband surprised me with this serger and I really like it. It's easy to use and works really well. I love that it has a removable arm in order to serge sleeves. My only complaint is that it doesn't have a cutting width guide to sew perfectly consistent seam allowances. The only guides are several unmarked notches to the right of the needle. I find them difficult to use to get a consistent and exact seam allowance. If a movable cutting width guide was added to this machine, it'd be the perfect machine!
