Orp gets a great review in Cool Hunting. This website covers products and projects that they deem as being nicely designed.
Have been using my Orp for one month now. The strap has developed some give and now sits snug but is easy enough to open to switch to another bike. One charge has lasted around 20 rides and only today has the low charge light started to flash. In summary: Orp is brilliant! A 10/10 product.
