The product delivered as advertised. I purchased the devise to monitor sound levels at a proposed business next door. The device allowed me to document noise levels that violate the local zoning ordinance and present the information to the planning board.However, the seconds on the display are defective. The numbers do not fully populate. For example an '8' looks like a 'z'.For a novice user, I wish the features were better explained. The documentation provides the purpose of the setting, but not what the purpose actually means. For example, select 'X' to do 'Y', but it doesn't explain why I want to do 'Y'. Thank goodness for Google.

I paid $80.00 for a digital product that does not turn off while pushing or holding or staring, shaking and straining the ON OFF BUTTON! I do not have time to send this back because we need this item to test ASAP a huge University during this weekend for a fire inspection on Monday. So, I have to unscrew, yes, you heard me, unscrew a screw and flip a battery over just to shut it off! I have not tested it yet, but right now I am not happy for this price! Is there really, this many incompetent companies out there that can't even get a simple ON/OFF to work right? $80.00?????? Is the Type 2 rating even correct? I'll change the score to three if it works and passes the State Fire Marshal's inspections!

Great price. Now I can get true measurements of system. I had been using an app on my phone and it was far from accurate.

I am having so much fun with this. Super easy to use. My hearing is not up to snuff and sometimes I am not sure whether my tv is too loud. I can now use this little thing and find out. If a neighbors noise is bothering me I can have an accurate idea Of whether its my imagination. Perfect for casual use, love it.

I have a 11.1 stereo system set up in my fun room. I have been trying to balance the stereo sound field to make the sweet spot even sweeter! If that is even possible? I`ve been adjusting the db levels on each and every speaker. It sounds rather balanced to me until I spoke with a sound engineer. I followed his advise and purchased this db meter. The results are nothing short of amazing. At least to my ears. From every direction with in the room sounds the same! This really worked out just great! The meter numbers ramp up and down the scale rather quickly, so it takes a little getting use to it. In my estimation this meter worked very well for this application. I also like the lighted LCD screen. I had to take a reading at what db level my head was about to explode! At about 122dbs. Ouch!! Then to top it off my stereo was at less than 1/2 volume. Just Right!!

OK, now I'm no audio technician so I can't comment on how accurate it is, but it seems to work pretty well to me. I measured several different things in my house. The loudest of which was actually our infant son who can scream a whopping 120 db when he's enraged! Wow, no wonder that hurts my ears!So far as how it works, it has 3 modes... active measurement, and a max sound, and a min sound mode. Pretty easy to click through to find the mode you want. It came with a 9v battery, and it feels solid and well built. It appears exactly as shown in the product image, and it has a back light for the display if you are in dark areas that comes on automatically. I'm pleased with this product!

This bad boy does a great job. When I need to confront my DJs and tell them they are playing too loud, the screen is big, bold, backlit and easy to read. Keeps them in line! The only reason I dropped a star is because it has an auto shutoff. While great for battery life, it is frustrating to have to keep hitting the power button when trying to mix for a live audience. It is also dark at our desk so I have to fumble around to find it and hit the power button.
