Why buy a streaming device when you have a smart TV?

Smart TVs and streaming devices both deliver services like Netflix, Disney+ and Hulu, but smart TVs vary widely in performance because manufacturers license software from Amazon, Google and Roku, leading to sluggish or buggy operation on older models. A dedicated streaming device offers newer, faster operating systems, fewer ads, more reliable streaming, and additional features such as local media playback, remote-control locators, live TV support, and gaming capabilities. Replacing a streaming device is a cost-effective way to maintain speed, reliability and software updates without buying a new television.
