Faulty Tachometer ruins your ride

After trying this product, I was extremely disappointed with its performance. The tachometer was inaccurate from the start, making it difficult to monitor my engine's RPMs. The only good thing was its waterproof feature. However, the faulty reading led to issues with my diesel engine, putting my Automotive safety at risk. This product may work for some, but it was a complete waste of my money.

Pros
  • Waterproof feature
Cons
  • Inaccurate readings

Scrap: Electrical

The item does not work. I connected all the wires according to the instructions and the tachometer needle went in circles. Another piece of junk from China

Pros
  • Rev counter
Cons
  • Other Other

Don't buy it, it's garbage!

Do not buy! It gets stuck and the RPMs are nowhere near correct. After trying to understand how to calibrate it according to the instructions translated from Chinese? I spent two hours reworking the dash to fit and it's utterly useless.

Pros
  • Electrical
Cons
  • Protection
