## Customer feedback

Customer feedback reports positive impressions of diagnostic capability, scan speed, the large display, ease of use and connectivity. Some customers describe it as good value compared with more expensive tools. These are reported experiences, not proof of compatibility across vehicles. The scanner’s stated 10.1-inch screen and broad diagnostic feature set may matter most to users who will make use of its advanced functions. Aggregate ratings are generally favourable but include a smaller low-star share, and the available evidence does not explain the reasons for those ratings.
- Positive themes: Customer feedback highlights diagnostic capability and functionality.
- Positive themes: Customers mention quick scans, a large screen and ease of use.
- Positive themes: Connectivity and perceived value are also reported strengths.
