It works great and is also rechargeable. It lasts at least 2 batteries in the camera. I did buy extra batteries for the camera. That is a must.
Only thing that bugs me about the WIFI remote is the switching between my android cell phone and the remote. I would think both could work in the same mode but no.
You set up your view and settings on the camera using the wifi in the cell phone and gopro app. Then at the bottom of settings you have to select "switch to wifi remote mode" this stops the wifi connect from the phone. If you wack the camera with a tree and need to realign(the thing is a tree branch magnet), you have to go in to menu **** to switch back to phone to see the camera view on the screen.
Small petty complaint but hey. The setup ain't cheap and I like to complain
