notes:
Torquemeter Philippines
1. its price is a lot cheaper than the original Hios Torquemeter but its quality is also very good, also its precision & accuracy is the same or even exceeds original Hios.
2. its price is just a little higher than the "copy Hios HP series" so no need to buy the "copy Hios". Sundoo ST series is highly recommended.
