Review on 🚀 K.A.T. Matrix 3-Axis Accelerometer for Boosting Car Performance by James Arellano

As mentioned, the arrow keys on the right side are very sticky. If you turn on your device and hear endless beeps, it means the up arrow key is stuck. If you see a "Reset" message instead, it means the down arrow key is stuck. The only way to release them is to press between the two buttons (pressing the opposite button only sticks one). This is a major design flaw that occurs every time the device is powered on. I'm not sure how they missed it. In terms of accuracy, the numbers from 0 to 60 seem to match what my machine's manufacturer says, and as expected, the machine throws an error when you slow down. during startup, so obviously *something* is working. For the price, it's probably worth it as the closest equivalent to this device is more than double the price (and doesn't offer the convenience of battery power).
