With the benefit of the CostCo return policy, I think I'll be picking one of these up. Already have a Harmony 900 in the family room (need RF for cabinet housed components). My wife will appreciate having a remote with a familiar layout in the den.
As for the return policy, here it is from the CostCo website:
We guarantee your satisfaction on every product we sell with a full refund. The following must be returned within 90 days of purchase for a refund: televisions, projectors, computers, cameras, camcorders, touch screen tablets, MP3 players and cellular phones.
I don't think this falls into any of the categories requiring return within 90 days.
