Excellent... for my purpose!!
the install diagram for battery placement failed to mention the was a orange silicone sleeve already on the product... got a laugh out of that finally...once we got it on... (choose to bypass the calibration as described as to technical for my use) very easy to use (limited to on, readings, off)... not using for any professional purpose... trying to get my children to use quieter voices... creating a feedback loop and a family goal... set it up on the top of the fridge...the kids are checking it frequently... has min, max and hold features... not using those
