Used on a radio to cut interference from LED lights and they don't work. Didn't cut the interference even slightly. Absolutely useless. That's why I'm returning them.

I ordered these clip on ferrite filters for use on my milling machine to cut down on electro-magnetic interference (EMI). While 9 of the 10 items worked fine, one of them wouldn't open...no, not the outer plastic shell, but the magnet within. It's like the magnet is glued shut... I couldn't pry it open or anything. Not good if you need to attach it to an existing cord with a plug end.
