Just happened to find this wire organizer and I’m glad I did. What a simple, effective and inexpensive way to hide excess wires.The small was like a mini to me.Computer cord, works OK!I use the small organizer in my car to wrap my phone's charging cord and an audio cord for my phone. I really like that my cords stay neat and organized. Before this, I had two things that were meant to wrap up cords, but even if I just moved them around a little bit, they never stayed organized.The pictures I posted show step-by-step how to use this organizer....1. It is somewhat difficult to open the turtle shell, but if it was very flimsy it wouldn't hold the wires the way you want it to.2. This is how the wires looked in my car before buying the turtle.3. I wrapped each wire around the slender middle of the open shell. The charging cord is a thicker cord; whereas the audio cord is a thinner cord. But both cords wrap around the turtle shell organizer with ease.4. Even while wrapping, but especially after the cords are wrapped around the shell, you have to hold onto them so they don't unwind.5. When you are done wrapping the cords, you slowly start to close the shell over them. The shell is stiff, but stiff in a good way.6. Both sides of the shell closed over the cords.7. Now move the wires to the small openings.8. The shell has 2 small openings, one for each end of the wires.9. This is how nice and organized my phone wires looked after using the shell.This whole process of using the shell took about 10 minutes to complete, so quick and simple. But oh so wonderful! A couple of times, I have noticed my cords were dangling with one end plugged in (not the fault of the shell organizer, just something I had accidentally done), but the shell held on tight to the cords and they didn't even move at all that I can tell.PerfectI like these Cable Turtle Organizers and I'm happy I ordered them. I use them constantly. While they are great for travel and storage, I like to use them around the house to shorten cords while charging electronics and of course storing them between charges. The mini is perfect for my phone. I use the small size for my toothbrush charger and to shorten the cord of a small room fan. I use the large size for my computer charger and it is plenty big! The mini is my favorite and probably best for my needs with the small size coming in 2nd place. If I had more large ones I would use them to shorten and organize cords on items such as printers, lamps and other electronics that are plugged in permanently but need the cords shortened and out of the way. They are very easy to use and seem sturdy and durable. I highly recommend these Cable Turtle Organizers for use as I've described.Our baby monitor camera has a 15' long power cord (not sure of the gauge) and fits in the small. Keeps cable tangle-free when traveling.These things do exactly what they say they do!!! They get rid of unnecessary loose wires and make the area look very asthetically pleasing! Well designed, secure, and durable! PS I only showed the small and the medium shells because the large one is a monster that cold several ethernet, usb, and/or power cables! 10/10 for sure you won't be disappointed.
