A good idea at the base, but in practice some drawbacks remain. Chemical smell that emanates from nine unpacking conveys at first, but mostly it: - Do not fit all smartphones. Learn much about the size. - Nest usable on the left wrist. - Is not practical to make calls. Emphasize the speaker. - Do not protect the laptop sweat. In short, unconvinced, but still this is better than having the laptop to move in the pocket!
