Santa was good to me this year, got a 5D Mark II for Christmas and started looking for a grip this morning. At first I didn't think anything of it and went straight for the Canon grip, however after some review reading it seems the Vivitar and other aftermarkets seem to perform well at more than half the price. Then I came across a Polaroid version, anyone have any experience with this unit? I haven't found anything online for it.
