Thanks for the positive response shape. The fact that I shelled out $20 for the damn thing and it doesn't work the way it's supposed to never crossed your mind I suppose. Ever thought that it could be a manufacturing problem that they don't know about yet?
Anyway my local RS is less than 10 min away, and they just handed me a new ZZ (no defect) with no paperwork or hassle.
Thanks for the help anyway...
