Seems well made enough (how tricky is it to make a ferrite collar?), but the actual inside diameter is less than 1/4", so I couldn't use them because they wouldn't close around my cords. I contacted the seller and they sent replacements, but they were the exact same thing. If you don't need the full 1/4", you should be fine. If you do, look elsewhere.

Edit: I've been able to use some of these on some cheap HDMI cables I bought, so that's cool.

2.0 out of 5 stars Poor Sizing and Locking Tabs Break Easily, March 18, 2010

I went to "easily snap" onto my power cable on my tv and the 2 locking tabs broke off instantly. (you can see them in the item picture) Even without much force, these things are fragile. I ended up wrapping it on there with electrical tape. Still didn't solve my noise problem but I don't think it's this products fault. However, 1/4" should be 1/4". The inside diameter seems just a hair smaller than 1/4", enough to be an issue. Customers may want to purchase the 3/8" size instead to be safe.

Well made item that is useful to keep on hand for troubleshooting noise problems, and as a solution. At this price, keep two on hand.
