This video was fun to make. Had a chance to test out what I believe is the World's smallest phone. It's so tiny that you can wear it as a headset, yet it's an entire phone with sim card slot! It also has a built in voice changer which is fun to play with. Some of the voices include Optimus Prime and Wall-e.
It seems like this device goes by a few different names including Sonica and J8 as well as Long-CZ.
