Works well. High visibility

Use this for our indoor rock band. Works well and is clearly visible. I want it to be battery operated and not have a 110 outlet. only negative.

  • Easy install
  • Not bad

Doesn't work - waste of money

Obviously not calibrated as even in a very quiet room with no conversations the settings jump around in the 40-50 decibel range. It was a big waste of money.

  • Very good quality
  • I'll add later

Great tool for band volume control

I hung this on the wall in our rehearsal room to control the volume of the band members. Works great - everyone can see it. I tested the accuracy with a calibrated handheld device. It was very close.

  • GOLS certified
  • Mostly good but...

Has NO AC adapter

I've been using it for more than a month and the numbers aren't getting tired in any way, even in a completely quiet basement. There is also NO power bank or battery to charge, although the description says you need a 'charger'. You will need to find your own 5v - 1 amp power supply.

  • Inspires confidence
  • Not fashionable

Good basic reference level meter, good safety for your hearing

Fast response time just means the reading is constantly changing rapidly. only negative! It would be nice if it had a slow response setting averaging a few seconds for each reading. All in all a great hearing protection tool in my music room for detecting guitar peak levels (turn the volume down!) lol

  • Excellent overall performance
  • Doubtful

I tried to love it. I've bought it twice from two different Amazon sellers and both were within 15+ decibels. I know this for a fact because I have several other finely calibrated handsets and read them in a perfectly quiet room in the 30's and these puppies are consistently reading 44 plus. IF you happen to buy a perfectly calibrated calibrator, or have the means to do so yourself, by which I mean own a certain precision calibrator that costs a lot, then you will love it. What I like about it:

  • Best
  • Ugly packaging
