Products value is over the top, for the cost. So, worth it. You will not be unhappy. So very easy to use and work.
The equipment worked great right out of the box. It was very accurate and easy to use. The only draw back is the laser only operates after the trigger is pushed, then the operator has to push a seperate button to turn on the laser. This is a little busy, but on the other hand it probable saves the battery (just guessing) Been using mine in a virety of areas, auto mechanics, home and auto air conditioning. Very happy with the product. Priced many other units before purchasing, This unit is comparable in price, but the Sears one year on the spot return policy sold me
I found mine is only about 2 - 3 degrees off. And also mine turns off just fine. Stays on for about 6 seconds after taking the reading then turns off. I don't know what everyone's talking about, (Maybe compertors), but overall this is a good product.
