Query: not too thrilled

While it's nice to protect the LCD, the lack of the ability to add a eyepiece extension makes it more annoying than useful. Your face is pressed against it more when you try to use the eyepiece and the LCD screen has to be closed to use it. I only use this to protect the LCD during transport now and switch to my eye extender for actual use.
