Remote is very difficult to open to insert batteries. Best way is to find a flat & firm surface; put an unfolded towel on that surface; put remote on the towel; place and keep index finger on circle indentation on the back of the remote; slide remote cover down at the same time. All done.
The only thing i don't like about the fire stick is that when you turn it off at the remote, your TV automatically shuts down as well. There is no way to override this. So, if you plan on watching a dvd or TV after streaming with the fire stick, be prepared to switch the TV back on again.
