KopyKake: Who uses them and what do you use them for?

I am looking into purchasing a KopyKake projector. I am a beginner at cake decorating and I am trying to find easier ways to make accents with fondant. As it is now I cut our a pattern, place it on the fondant and cut out the pattern with very shape blade. Problem is sometimes my patterns stick to the fondant or they just get int the way. I was hoping that using a projector this will help me make cleaner cuts and be able to be more creative with my patterns. I was hoping that if you use a KopyKake you could share your wisdom with a newbie who is a perfectionist and is driving herself crazy with things do not turn out as clean as I hoped for! I would love photos or hints that woud help. Thanks!!
