Anyone ever used "Real Magic"?

[Hookmanski]

I got a can of this stuff called "Real Magic" as a stocking stuffer fro christmas this year. Apparently you spray this stuff on your line on the spool and it increses casting distance, prevents icing, reduces line memory, etc. Seems like its some kind of line lubricant. Anyone ever use this stuff? Does it actually work or is it more of a "gotcha" product?

Side note, i also got a pair of waders, so expect some trout reports soon! Hope everyone has a happy and healthy new year.
