Normally if you want to take a picture of someone, it is pretty obvious by how you are holding the camera and where it is pointed. Everyone knows that you are doing it and they know who the target is. This iPhone periscope will help you keep things undercover.
The idea is that you install a sticky metal ring on your phone, so when you want to use the periscope and be sneaky about taking pics, just place the periscope on the metal ring. There’s no need to install any software or anything else. A mirror inside the gadget just reflects the image into the lens of your camera.
So you just pretend that you are playing with your smartphone, while you are really taking pictures. It is only $22.45(USD) from allputer. Hopefully that sticky ring is strong enough not to make you look like a bumbling inept spy when the periscope falls off.
