Excerpt: This is one product that requires name-branding from my experience. I have had off-brand grips before, and found them lacking. My only flaw thus far, is needing to have it powered on to use in vertical fashion, but that's minuscule.
Excerpt: I bought this item to use with my newly purchased Canon 6D. I knew I needed something that would allow me to shoot longer as well as add balance to the camera. This product is great because it definitely makes the camera feel more balanced and stable.
Excerpt: I've never used one of the off brand versions so in any speak to those. I bought it for a new camera so I preferred to use brand name. It works great, installs just like the other ones I've used on ither cameras. I think the battery door holder is actually much better than the one in my 60d
