I purchased this grip for use with a Canon T5i. It fits well, all buttons work well and the whole thing feels nice. It comes with two power cartridges - one for 2 LP-E8 batteries, and one for 6 AAs. Both work well! However, it isn't perfect: I discovered that stock Canon LP-E8 batteries do not function in this unit. The battery has a lockout feature, and will not provide power until it detects it is in the camera. The grip cartridge has a third pin, presumably to trick the battery into thinking it is in the camera, but this does not work with new batteries. I just had to purchase some knock-off batteries without protection circuitry to make it work. Keep this in mind before thinking your unit is defective. The grip helps make footage more stable when using your camera in video applications. The wider grip area allows for a more secure hold. I did a full day of shooting with it, filling a 16GB memory card, and it performed as expected.

as advertised works good

I had to replace one of these already after it started to separate. No issues with the return and exchange. I guess you just have to be super careful with them. Besides that, it works as intended.

Every thing I have purchased from photogear has been awesome except this item. Had it for a week on my t5i and it just started falling apart. Very bad construction. Some screws fell out and now it wont work. Dont buy this item it is crap.
