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.

My remote caddy
Color: Black, Size: Small
I have so many gadgets that uses remotes, my end table looked awful with remotes everywhere and when I would move something, a remote would fall off the table. It was aggravating but now I have a nice caddy to sit on my table and it holds all of my remotes. It's beautifully designed and was shipped to me very quickly. I think it was in my mailbox within 24 hours. I'm very pleased with the item and the person I purchased it from was quick to get it to me. Thank you.

Great product
Color: Black, Size: Small
This is great to store multiple remotes in a small footprint clearing up table room. My 6 year old Grandson loves it also keeping remotes in one area. He operates the TV also. We loved it so much we bought a second for another room.
