Sweet accessory but be careful!
I absolutely love my GoPro Hero2 so I bought the LCD BacPac so I could see what I was shooting. It was awesome and worked when I was testing it out and then the very first time I went to really use it on a snowboarding trip the LCD BacPac just didn't work anymore. In the process of hopefully getting it replaced. I researched it some and seems like this exact problem has been happening a lot with the LCD screen unfortunately. Just thought I should put a warning out there. It was sweet when it worked tho! Maybe you'll be luckier than me.
