I run a club and use this to make sure we're not exceeding noise levels in our zoning area on nights with DJs or bands. Its small, light weight, portable, and so far has been accurate. It's not hard to usethis is the first one I've owned. It's handy to have and didn't cost much.For as inexpensive as this product is you would think that it would be feature-limited. You'd be incorrect, however. This SPL meter easily keeps up with the bigger and more expensive toys we have. My only complaint is that its upper register is only ~105db. But at that level you should know it's too loud!I compared this meter with a well-calibrated professional one, in a carefully established sound environment. I examined all ranges or settings and different sound levels. Whereas the professional meter was completely consistent and repeatable in all cases, this Pyle meter often gave random readings that that were slowly increasing or decreasing. When I could get semi-stable readings on the Pyle, they tended to be 20 db or more lower than those on the professional meter. I put in a brand new battery, but that didn't help. The word OVER was constantly displayed on the screen, even when I was dealing with no more than 50 dB. Unfortunately, the meter did not come with any instructions. Part of the problem may have resulted from shipping, as the meter arrived between two pieces of cardboard with no padding of any kind. If you purchase this meter, you should have the calibration checked before relying on it.Did not perform as expected. I had readings all over the board. I ended up returning the product, so hopefully this was a defect and not average performance.At first glance, the SPL meter almost looks like a toy. However, it is an amazing product. I bought it primarily to check for sound levels from my receiver to set safe sound levels, but I was able to use it to verify the Audissey XT balancing that the receiver performed. At the test spot which I used to balance the stereo, the Pyle SPL showed a consistent DBA rating for all of the channels. DBC ("C" weighted decibel) is used to balance stereo systems, but I was able to verify that from a human ear perspective the noise level at the listening post would not exceed 85 dba by setting a max volume that produced sounds close to this range on the receiver.Highly recommend that one gets an understanding of how "loud" safe listening levels really are using an SPL meter.
