Great product.

These are cool looking and add a cool detail to the LC70 body. The window feature does not work well though. You can build the moving mechanism and it will work perfectly. Once you attach the inner door panel to the door the windows jam and the gears cog. I had this with both windows. I would think there might need to be a tolerance change. I would also recommend that Killer body change the method of attachment from glue to screws to make repairs to the windows.

Well, without problems of installation.
