Review on 🚗 ESUPPORT Car Tachometer Gauge Meter 2" 52mm Tacho RPM Pointer with Blue LED Light by Johnathan Delic

For the price and judging from a lot of reviews I didn't have high expectations for this wheelbarrow. To my pleasant surprise, it actually works very well! I compared the tachometer readings with an OBD scanner and found that the RPMs were almost the same. Pretty impressed with this little sensor given the price. Although the instructions were rubbish. Just one sheet of poorly designed paper for all the sensors this company makes. There were no instructions on how to properly calibrate the tach - I suspect that's the problem with most of the reviews here. They have an adjustment knob on the back and you have to set the right number of cylinders for the tach to get the correct reading. Without instructions, it took me a while to figure it out. Overall I am very satisfied with the product!
