### ⭐⭐⭐ 







  
  
    Have not fully tested it yet
  

*by C***R on Reviewed in the United States 🇺🇸 on April 18, 2022*

The product seems to work as advertised, by delivery person seems to have thrown it over the fence into my concrete driveway and the product did not come packed in a box so the impact was hard enough to damage the batteries that were included to the point that one was too damaged to use.  The item was shipped in an envelope.  The envelope was marked "this packaging is lighter than our smallest box", but when you are shipping something as sensitive and fragile as electronic instruments, it should really come in a box.  So far the device appears to work with batteries that I provided, and there is no rattling sound or visibly cracked areas, but gonna check operation for a few days and if anything is amiss, I would expect an exchange for a new unit.  Preferably one shipped in better packaging.

### ⭐⭐⭐ 







  
  
    Good Product, BUT
  

*by K***R on Reviewed in the United States 🇺🇸 on November 5, 2021*

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.

### ⭐⭐⭐⭐⭐
