I’m extremely impressed with the quality of this product. It’s very well made, feels tough and built to last. The packaging it came in looked really great as well. It comes with a manual, a set of batteries, and very nice probes. The batteries have to be inserted by unscrewing one screw which was easy enough. It also has a stand which unfolds from the back which was a nice surprise. Tested it out on a few household batteries and accuracy was spot on. Really an amazing product, thoroughly happy.
