THESE TWO REMOTE CADDIES ARE FANTASTIC
Color: Beige, Color: Beige
I bought both of these caddies. Picture 1 shows it in my living room - TV Remote, Cable Remote, Ceiling Fan Remote and glasses. I love the little handle that I can pick up when I need to clean the glass table. Picture 2 shows the three slot remote. I put this in bed with me at night. I am older now and I need my phone on my bed at night so in this caddy I have my phone and ceiling remote fan. Also it is a good weight so it will not fall. These caddies are so well built and so nice to look at. If you need a remote caddy you will love either of these.

Perfect!
Color: Beige
This is everything it appears to be in the picture. It's perfect. it's practical. The one that looks similar but comes on a rotating lazy Susan base is very small in the holders or pockets I don't recommend it.

Love this little remote caddy.
Color: Black, Color: Black
First, it's very nice and compact and sturdy. I would measure it before you purchase. I like that it's small. But if you have a lot you want to store, you may want to size up. It works perfectly in our house for to keep our essentials organized.

So luxe
Color: Cream
I bought this not expecting a lot. I just wanted something to be able to carry my lotions from room to room in lol. I don’t like clutter and I like things to have a place so that’s all I was looking for and this was going to live in a cabinet when I wasn’t up and about around the house. This little caddy looks so luxe though! I just leave it on my coffee table sometimes and it doesn’t bother my soul lol… it would be a great remote holder. If you don’t mind them showing a little bit lol and I really think this would make a really nice bedside caddy which is partially that used. I was going forward with this would buy this again and again.
