Great invention
Color: White
Second pack of these and I love them. I used them mostly for computer cables in my home office and my work office so I did not constantly have to go digging for laptop power cords and adapters. They have a strong adhesive that is very durable, the installation was super easy, super functional and overall great value for the money. These would be versatile as well if you wanted to use them for say phone charging cables or similar cords that seem to always fall behind a shelf or something similar.

Wonderful for chargers
Color: White
I was skeptical about ordering these, but I am so glad I did. They are little cord controllers and they have a lift up cover that is magnetic so you can easily take your cord out of the hole. They stick to what you put it on and I’ve had no problem with them coming off on wood or plastic. Glad I bought these.

Easy and Effective
Color: White
These are slick little gadgets! They hold a cord so it doesn’t fall behind a table or chest. I affixed one to the side of our nightstand and my phone charges there all night. Genius- no installation skills required.

Perfect to plug in and off the floor.
Color: White, Color: White
These are perfect for keeping the charging cords organized. I have difficulty reaching the floor when I need them. I work from home and need to charge my phone and laptop often. So far the adhesive is holding up. The magnet is strong enough and the cord is light weight and does not slip through the hole. I have usB and C cords. We use them at the side of bed for our cell phones. It’s on the side of our nightstand. Makes vacuuming easier to. The cord is off the floor. Overall happy with these. Worth the money.

Overall good
Color: White
These work pretty well and adhere securely. I chose to stick on the underside lip on my nightstand in case it damages finish. I like that they pop open to remove cord when desired, although sometimes it opens when I pull on cord too hard. Overall, I think they are help and save me from rummaging around for my cord.
