Super lightweight and dead accurate! I used RebasGre to measure loud neighbor noise and the max/min hold feature gave me undeniable proof. Absolutely worth every penny.

The backlit display is so easy to read in dimly lit studio rooms. Fast response mode instantly spots sudden acoustic peaks. Extremely handy tester for work.

Great build quality for weighing only 53g. The analog bar is intuitive and the auto shut-off saves battery life during long fieldwork sessions. Highly recommend this decibel meter!
