I can't figure out how to open the battery door; the instruction manual doesn't display where that is, nor how to open it; I had to come back to the product listing to see images of where the battery door is, but, sadly, I cannot open it still. I have pressed into both indentations as once as hard as I can, and then with my other hand tried to pry it open and down, but it will not budge. Thank God I don't need to use it right away cuz I'd be in deep trouble! I wish you all would post up a video showing how to open it. If seller can let me know that would be great, I don't want to have to buy some other brand that doesn't have this problem (I hope it doesn't!).
