Roku just revealed its newest streaming sticks, which replace its Express streaming devices and fix an annoying design flaw.

The new Rokus, which cost $30 for HD resolution and $40 for 4K, replace CNET's favorite streaming devices without raising the price.

Roku revealed two new streaming devices at an event in New York. The company says its Streaming Stick and Streaming Stick Plus are the most compact on the market, measuring 35 percent smaller than other brands' models.
