Score: 85/100
Amazon Fire TV Cube
Score: 83/100Rankings
The MECOOL KM2 is a compact Android TV box that delivers certified 4K HDR streaming with Google Assistant and Chromecast integration. Its main trade-offs are limited Ethernet speed and modest internal storage. It is best suited for users who want a budget-friendly, feature-rich streaming device for mainstream media consumption.
The Amazon Fire TV Cube is a hands-free 4K streaming device with a powerful octa-core CPU and full HDR/Dolby Atmos support. Its bulkier form factor, lack of gaming-focused features, and ad-laden UI are notable trade-offs. Ideal for Alexa-centric households that value voice control and HDMI switching.

Professional reviewers commend the KM2 for its solid build, compact form factor, and Google-certified Android TV experience, emphasizing flawless 4K HDR streaming at 60 fps and the added value of Dolby Atmos and Chromecast integration.
Professional reviewers praise the Fire TV Cube for its powerful octa-core CPU, comprehensive HDR and Dolby Atmos support, and the unique hands-free Alexa with HDMI input that simplifies switching between streaming and live sources. However, they note the mediocre SDR upscaling, lack of gaming-focused features like VRR/ALLM, and a bulkier form factor compared to slimmer competitors.
Everyday users consistently highlight the convenience of hands-free Alexa, rapid app launches, and excellent 4K/Dolby Vision picture quality, while expressing frustration over intrusive ads, occasional voice-recognition hiccups, and sub-par upscaling of non-4K content.
