This week's gadget is the Selfy. It's a case for iPhone or Samsung Galaxy S5 that has a bluetooth remote shutter button. The shutter remote slides into the back of the case and you can slide it out anytime you want to take a selfy. They have accessories to fit into that slot including a tripod, bike mount, and helmet mount. It's great for parties and picnics if you take a lot of selfies.
Check out the Giz Wiz Video here. It costs under $50 for the phone specific cases, and the tripod is under $20.
