Roku can limit your bandwidth usage...

This is something I don’t think you can do with competing set top boxes - specifiy a maximum connection speed for streaming video. Could be very useful (and I’ve confirmed it works with a latest-gen Roku stick...)

Thanks for this tip!! I was not able to reliably watch Amazon Prime Video on Roku, but setting my max speed to 3.5 Mbps solved the problem!
