If you get a "Didn't work for me," ask admin to remove it. Bet they will.

I post reviews when I use the item. It wouldn't make sense to post reviews otherwise, would it? And sometimes I don't use items for months. I buy when it's on sale, when I have a coupon, not necessarily when I have the time or inclination to use the item.

And people do return things to Wal-Mart six months later. Heck, they come back a year later sometimes.
