The motion sensor on my 880 seems to have gone south--I now have to push a button to get the remote to wake up. Merely picking up the remote no longer does the trick.

When I bought the remote at Best Buy during the summer, I got a product replacement plan along with it. I can't decide if I'd be better off going to BB for a replacement or if I should contact Logitech for service...I'm wary of being blackballed by BB if I need to replace it again in the future, since it's now so early (relatively) in the lifespan of the plan. Any thoughts/experience/advice on the matter? It'd be much appreciated...
