"A surprisingly fast smart TV experience bolted onto a deeply mediocre 720p screen."
'HD 720p' means the picture has less than half the pixels of a standard 1080p 'Full HD' TV. User interface elements will appear sharp, but video content will lack fine detail.
This is a functional choice for a kitchen, workshop, or kid's room where the priority is a fast interface for streaming apps, not critical picture quality. Its price and responsive Fire TV OS make it a capable second screen.
Anyone seeking a primary television for a living room should avoid this. For a marginal price increase, 1080p and even 4K 43-inch models from other brands offer vastly superior picture clarity. The 720p resolution is a significant compromise.
