This little clip attaches to your mouse pad. You run the cord through it leaving a loop of the desired length and it ends the drag you get when the cord tends to pull against the mouse.
I don’t remember where I found this, but I’ve used it for years on the computer that still has a corded mouse. I like it a lot. The idea is really simple, but it really works.
You just slide the clip itself on to the back edge of your mouse pad, and then push the mouse cord into the cord holder part that sticks up. The whole unit is about 2.5 inches x 1.5 inches. Once you figure out how much play in the cord will work well for you to give you the freedom of movement you desire the cord will stay put right there, and never cause that really annoying drag that makes using the mouse a chore.
It will work with a standard size mouse cord. The very skinny cord on my Mini Mouse
is too thin, although if I really wanted to use it with this I could tape the cord onto the clip.
I have located these on line from a distributor in New Zealand, but it’s not clear that they are still being sold in the United States. (Their patent may have been denied, if I am interpreting some info correctly.) The klip says ACI Computer Accessories, but they don’t seem to have them. It’s really a shame if they aren’t available here, because it really does the trick!
The New Zealand wholesaler is Phoenix Solutions
