I paid a few quid for this, just to try to have a back up for my BOSS BR-600. (A digital music recorder)
It arrived quickly and well packaged, I formatted it on my PC and it worked perfectly on the BOSS.
I had already ordered an "original" memory card for the BOSS and paid through the nose for it, my advice would be to buy yourself a "spare" at this price, as they are becoming more difficult (and expensive) to get a hold of.
