Perfect for me.
Color: Black, Size: Small
I was a little trepidatious before opening it all up and checking out the holder. I didn't know whether or not the larger remotes I had would fit. How would it work for the bulky / longer TV and Universal Remotes. It worked perfectly.
The holder is small enough to use on a small side table next to the couch. And it's very simple to access. The living room now looks like a living room...rather than Radio Shack gone biserk.

Simple and Effective Remote Organization
Color: Black, Size: Small
The Pros:
Spacious Design: With five deep pockets, there is plenty of room to store everything from TV and soundbar remotes to reading glasses.
Functional and Steady: It sits perfectly on a side table without tipping over. It does exactly what I hoped it would do by keeping all our remotes in one spot.
Great Portability: It is lightweight enough to move around easily, which is helpful for keeping things organized while we are on the move.
Clean Finish: The material looks professional and blends in well with the furniture without looking like a cheap plastic holder.
The Cons:
Pocket Depth: One thing to keep in mind is that the pockets are fairly deep. If you have very small remotes, they can slide down a bit far, making them slightly trickier to grab quickly.
Bottom Line:
This is a straightforward, no-fuss solution if you are tired of losing remotes in the couch cushions. It is well-made, looks good, and simply works. I would definitely recommend it to anyone looking to declutter their living space.

Nice look, perfect size and great price!
Color: Black, Size: Small
Absolutely perfect for 5 remotes. The bins are deep and very wide. It's a very reasonable price and it's compact size fits in smaller spaces so it doesn't take up a lot of room. Also, you can't beat the price and genuine leather. Good in any room.
