Great purchase - don't bother with normal ebay magnetic strip unless you need it for paper
I bought some magnetic strip off ebay for organizing tools etc but it was next to useless with almost no holding power. After looking around I brought neodymium strip from AMF Magnetics. Obviously more expensive, but the holding power is night and day different to the ebay stuff. I have cut this strip up and using it for holding sockets down. It is only magnetic on one side so I am gluing it down. It has great holding power and not much is required.
