Good Scanner, No Topology Update Option

This OBD2 diagnostic tool works well overall, but it was returned because a topology update was not offered. The scanner is otherwise described as nice, and the main frustration is that topology capability could be provided but is not. Shoppers who need topology functionality should confirm availability before buying.

Pros
  • + works well as a scanner
Cons
  • − no topology update option
  • − topology capability not offered despite being possible

Great Scanner, Accessories Are Just Okay

The scanner is quick, easy to use, and highly portable, with a wireless dongle for OBD2 and some bi-directional reprogramming. It receives frequent updates and includes AI help via Wi-Fi, though that relies on overseas servers. It does not replace dedicated systems like FORScan or MMCodingWriter. The included accessories are only adequate: the screen protector hinders touch response, the key programmer handles basic cloning and configuration but not creating new keys, and the endoscope lacks the high-definition quality needed for detailed inspection. The scanner alone is excellent value, especially at its current lower price.

Pros
  • + Quick and easy to use
  • + Portable with wireless OBD2 dongle
  • + Bi-directional reprogramming support
  • + Frequent module updates
  • + AI troubleshooting assistance
  • + Great value for the price
Cons
  • − Screen protector impairs touch sensitivity
  • − Key programmer limited to basic cloning and configuration
  • − Endoscope lacks high-definition resolution
  • − AI requires Wi-Fi and connects to overseas servers
  • − Does not replace dedicated systems like FORScan or MMCodingWriter

Great Product, Delivery Left Package Outside

The product itself is great. However, the delivery experience was poor, as the package was left outside the post office. The item meets expectations, but the shipping method left something to be desired.

Pros
  • + Product is great
Cons
  • − Package left outside the post office

Works as described at a great price

This OBD2 diagnostic tool performs as advertised. It displays all types of codes and downloads updates automatically over Wi-Fi. An attempt to calibrate a wastegate actuator was unsuccessful, but the prompts and functions appeared to work correctly, suggesting the actuator itself was the issue rather than the tool. Heavy-duty maintenance tasks have not yet been tested. Overall, it does everything it claims to do at a price that is hard to beat.

Pros
  • + shows all types of codes
  • + automatic Wi-Fi downloads
  • + functions and prompts work correctly
  • + great price
Cons
  • − wastegate actuator calibration unsuccessful (likely due to actuator, not tool)
