Review on 🔌 Efficient Phase Testing with Extech 480400 Phase Tester by Bubba Ott

This unit is great for security as all the wires are very well done. The terminals are covered and the risk of exposure is very limited due to the design of the product. A well thought out product that is very easy to use. Also comes with great instructions to clear up any questions you might have. Works consistently in hot and cold and has never given us a problem to date and that's hard to say for a lot of products these days. A solid A!
