The design receives a high score of 85, highlighting its seamless integration into various interiors. Regarding user experience, the score of 70 indicates general satisfaction, although the lack of Smart TV is a drawback. Connectivity is deemed versatile, but the score of 65 highlights possible complications related to weight and the limited number of USB ports. In summary, the Grundig 55 GHU 7970 B is an interesting choice for those seeking good image quality and an attractive design. However, it is important to consider its limitations in terms of smart features and energy efficiency.Score details
