GREAT REMOTE HOLDER BUT BEWARE OF POSSIBLE STRONG PERFUMY SCENT!
Color: Black, Size: Small
This is a very nicely made and attractive remote holder, perfect for my storage and organizational needs. It is a good value for the money. The only reason I did not give it 5 stars is that the small pack that was in the holder to prevent moisture had a very strong perfumy smell that gave me a headache even after I removed it and left it in a place away from me to air out for over a week. I can still smell it, although it seems to be gradually fading. I would have returned it and ordered another but figured I would get the same situation so it would not be worth the trouble.

Good product
Color: Black, Size: Small
So far so good. It has enough spots for remotes, seems to be good quality and works well. Its staggered height of the pockets works great and looks fine on the end table.
