5.5'' Car HUD Head Up Display with OBDII/EUOBD Interface Diagnostic Monitor System, Water Temperature, Fuel Consumption, Engine Speed, Over Speed

The 5.5'' Car HUD Head Up Display with OBDIIEUOBD Interface Diagnostic Monitor System has received mixed reviews from customers. On the positive side, users found the display very easy to set up and appreciated its bright and beautiful display. However, there were several significant issues highlighted by customers that detracted from the overall experience. One major downside was the slow update speed for the MPH and RPM readings, which updated at a rate of only about 1x per second, making it difficult to keep up with while driving. Additionally, while the speed display could be adjusted to MPH, other calculations such as fuel Consumption and remaining estimated liters were only available in metric units, rendering them useless for American users. Furthermore, some users found the RPM display to be inadequate, with only a scale provided rather than an actual RPM readout. This limited functionality made it challenging to quickly glance at the information while on the road. In terms of durability, some customers reported issues with loose ports after a month of use, requiring them to use duct tape to secure the connections. This led to signal loss and, ultimately, the device becoming unreliable. Overall, while the HUD display offered a range of information and features, the product's limitations in terms of update speed, unit conversion capabilities, and durability concerns make it less than ideal for users, especially in the U.S. market. **
