This is the entry-level HD version of the Amazon Fire TV Stick, which does not support 4K. I couldn't tell the difference from 4K when watching on a regular TV. MODEL NO. S3L46N (Confirmed) Set includes Fire TV Stick and voice remote, compatible with Netflix and Prime Video. I have hardly used it since opening the package. I have confirmed that it starts from the initial Wi-Fi setup screen when connected to a TV. I visually confirmed the model number engraved on the device and, based on that, verified the following with AI. I am not an expert, so I prioritize the current photos. Key features include: Full HD (1080p) streaming media player, not compatible with 4K. Alexa-enabled voice recognition remote control for voice operation. Dual-band Wi-Fi (2.4GHz and 5GHz) for stable connection. Regular Fire OS updates add new features and enhance security. Some remotes support TV power and volume control, but often have fewer buttons than 4K models. The CPU is made by MediaTek, and while the performance is less than the 4K model, it has sufficient specs for everyday use.
