Yoshi Copper Grill Mats

Just saw these advertised on the tellie, has anyone here tried them?  They'd be pretty good for cooking small things like shrimp and veggies, but from the videos it looks like you do get grill marks (heat from the grate bars zips thru the mat to blacken the food) but it blocks any radiant heat from browning the other surfaces, I dunno.  Looks like they'd be easier to clean than the wire basket I currently use for shrimp/veggies.  
Googlez tells me Target has these for less than $10, but you don't get that cool "Flip-n-Grill" tool shown in the OEM site above (it would look so good next to my turnip twaddler).  I have no financial interest in Yoshi.

I’ve used them once. Worked as advertised. Does slide way easier than expected.
