This cleaner worked about two times, never would rewind properly - now it has completely broken my favorite VCR beyond repair... and I know how to fix things, this can't be fixed!  If you buy this head cleaner then you are one brave person!  This item cost about $11 bucks, plus another $99.00 tom replace my now broken VCR!  Junk!  By the way, what happened is it got stuck - i mean really stuck good!  Removal was impossible without damaging the VCR.
