About This Fire TV Cube Specs Sheet
As part of the due diligence in preparing our reviews for our blog, I noticed that full, detailed specs for many products in a tabular format were not available online. While the vendor and even major review sites like CNET provide limited detail, no site provides a comprehensive level of specifications datasheet detail on a single page. Our aim is to remedy this with this new format.
Please leave us a comment below and let us know what you think. If you have thoughts for improving on this format, we would love to hear those as well. Thanks!
