First of all, this device is slow and sometimes fails to respond to button presses or lags badly.
Second of all, the amount of built in advertising is extremely annoying. They literally make it difficult to not accidentally click on promotional items and rearrange the menu occasionally to increase the chance that you open a different app than the one you wanted. Recently they completely hid my Plex app because they apparently don't want me to stream using Plex. They instead pushed all the Amazon apps to the top of the list.
Today the Alexa voice recognition is spitting out results approximately 45 seconds after I give the voice command using the button on the remote. Complete garbage.
Two stars because you technically can watch content but my goodness they make you work to get to it.
