Helped a lot to reduce air conditioning noise in my house, dropped it from 37 DB to 20

Lot of choices for these mics. This one works great and is a good value for the money

I really like this product. It helps me know when my voice is loud enough.

Unfortunately the reader is not calibrated accurately and does not record accurate dB readings. I have compared with 2 other readers and it is consistently different.

I used it to check the exhaust noise on my bike prior to getting an out of province inspection completed, the device told me it should just pass the noise bylaw and it did indeed pass so I'm assuming it was somewhat accurate.

Showed up next day and it put a smile on my face. Easy to use and clear instructions. The only place I'm lost at is the plug they sent that looks like it's for a mic. Maybe to charge just don't know how to use it. Works like it should plus a six months warranty. Couldn't be more satisfied!
