I am very impressed with this dB sound level meter. It's sturdy, feels premium, and appears to be very well made. The large LCD display is easy to read and the backlight makes it even easier to read. I did a calibration test and its accuracy is +/- 2dB. It took me a minute to realize that the yellow rubber boot had come loose to get to the battery compartment. You can use the meter with or without the yellow rubber case.
