I just saw this when I went to buy a couple cheap QR clamps+plates, they're $9 cheaper than normal.

This is *supposed to be* compatible with manfrotto QR video plates (according to cheesycam). I can't vouch for this until I receive them. I hear the clamp takes an extra twist than the manfrotto, so it won't be as useful on a cheeseplate (since it wouldn't turn a full 360 degrees).
I don't think the TENOFF coupon code works anymore, but forgot to try it. If you miss this sale, there was one a couple months ago, so they probably go on sale every now and then.
