well it is as thn as your recording device. the lens is small. lke a pea size. plan to hotglue some foam on the front. as far as the lens there is a 2-3mm gap between the lens and hole for it. if there is a 1 in a million chnace the lens gets hit, there wont be direct contact. thats whyi made it a little thick.you dont notice it tho cause its pretty much inside the hopper (picture 2)
