Akira judges gear by real measurements and usability, so this one shines on value. Up to 113 dB for 3,980 yen with seven vibration-sensitivity levels is a realistic design. Never rate gear on looks alone — the dividing line is whether it fits 20-44 mm bars and carries IP66. No wiring, so anyone can fit it. Theft is too late once it happens; this is cheap insurance.
