The feedback surrounding this product reveals a frustrating experience for customers, primarily due to the technical issues associated with it. Many users reported receiving defective units, which either failed to power on or had malfunctioning displays right out of the box. Despite the presence of a "QC passed" card included in the packaging, there seems to be a significant reliability concern, as two different customers experienced dead units and others noted that they ultimately had to resort back to their old systems. Additionally, while some customers were able to get the unit working, they expressed dissatisfaction with the setup process, particularly noting the lack of English instructions, which made configuration challenging and time-Consuming. This was a point of contention for customers hoping for a smoother experience. Overall, while there is potential for the product, as hinted by a few positive mentions, a substantial part of the feedback highlights critical flaws in quality control and user support that have detracted from customer satisfaction and usability. **
