Core 77 is a website  by and for mostly industrial designers but mow covers multiple aspects of design.
They covered Orp in this first article during the  Kickstarter campaign.

“And I love Orp! I’ve been in a number of situations before when I wish I had something like it so I’m excited it could become a reality.”

I ring my bell all the time, but it’s not loud enough! I sometimes want a real horn, especially around cars. The Orp looks really promising and could help level the playing field out on the roads.
