I am an HVAC Tech. I found this to be the perfect meter for me!Pros:Great price for both! Very nice carying case. Great battery life, (so far 5 months on one battery).Cons:The yellow/black pipe sensor addon broke after using it for about a month. The wires pulled out of the sensor tip. I am unable to order a new one on amazon. I am now using the other temp sensor.I dropped the IR Thermometer once, and the battery never went in correctly again, I needed to put a piece of cloth to hold it in. I think something broke internally (ya i know my bad).5/5 star. I love this thing!
