The meter is really huge physically, especially with the case, I didn't expect the size so be careful if you are looking for something elegant to carry in your jacket pocket.
Otherwise, it seems reliable and precise, it's my first SPL and I love all the different functions it has such as calculating the noise level of specific sounds where the meter will subtract the general "room" noise and make the calculations automatically for you. This can be really helpful in certain situations.
I have mainly bought it to be able to calibrate speakers and have consistency and a solid reference when working in different studios.
Before I was using an application on my iPhone and obviously, this meter is a better option.
