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.

Sleek and spacious
Color: Black, Size: Small
Perfect for those who have multiple remotes and need a single place to stow them away. Material is leather like, firm and has a texture design. It suits well on a countertop or end table. It is not petite.

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.

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.
