Lure Retriever

[Dr G]

Do any of you use lure retrievers of some kind or another? I read about a product called "Ultimate Luresaver" which is basically titanium split rings that you use to replace the existing ones on the lure. According to the product description:
After removing your standard split rings and rigging the appropriate LureSavers the system is designed to break away when desired. When your lure becomes snagged you point your rod tip towards the snag, reel in all the slack, and thumb the spool, then turn your face away from the snag and pull steadily. At this point the LureSaver's titanium ring will open up and abandon the snagged hook, and release your lure.
That sounds pretty clever (though a bit pricey.) Has anyone used these or some other lure retriever that they would recommend? The idea of a lure retriever never occurred to me until I started looking at some of the more expensive lures like Lucky Craft. I would not like to avoid throwing into cover because I was afraid of losing a lure. So if these work they would certainly be worth the price.
