First, I am having the same problems a lot of people have had, which is, I cannot get the battery cover to close completely. It is 99 percent closed, but that is not enough to put in the screw. I am afraid if I turn it too strongly I may damage it, but to be honest I have been using a lot of strength , but is still won't buge.
Also, my lightsaber has a tendency to make the powerdown sound even when I haven't touched the switch after turning it on.
And one other thing, I have been having difficulty getting it to make the clashing sounds. So far I have just been hitting it against the palm of my hand, but that doesn't seem to trigger the sound.
I am wondering if this is normal, or if it should be sent back to Master Replicas to have these problems repaired.
