How dumb I was... I just found out last week that the Muse I received came without the lock. Lock is missing!! Neiman said they'll inquire for a replacement part, but I have a return due date to meet. So... I asked if I can get a disocunt w/o the part if I keep the Muse. They will only give a 10% discount. Should I keep it or return it? And is it easy to get the part? Thank you all!
