I have two D80's and only had this grip for one of them for a while...and found myself never using the body that was without the grip. So I finally broke down and got the grip for the second body.Not only is this a must have for stability while taking pictures, but the verticle shutter release is something I don't know how you could go without.The battery options are also nice, with having the ability to use two batteries for extended picture taking, as well as the ability to use AA batteries if you need to.The only reason I didn't give this item 5 stars is due to the price.In summary; would I buy one again...I already have!
