I just called SU and they are allowing me to return it. Bummer. It really is a very nice trimmer. I highly recommend it. (Let's face it, who else is going to have the problem I did?)
For now I am going to have to just stick with my old SU trimmer. They don't make that model any more but I called Fiskars and they told me any blade refill made for an "I" style triple track trimmer should fit it.
