Review on HQRP Sequence Rotation Indicator Detector by Justin Steele

This phase sequence tester is great for me. I use it in 3 phase 120 volt (60 Hz) circuits. I've seen diagrams for phase rotation testers and since only a few parts are needed there's absolutely no reason to pay more for one than it's worth. I find it strong enough for normal use and the wires are good quality. However, the case it comes in is too small and it is very difficult to put the tester, wires and clamps back in place. I plan to buy a camera case large enough to make inserting and removing the tester quicker and easier. I threw the UV tester in the trash. From what I've read about it elsewhere, its useful life is only a few days. That's probably why it's included for free (they couldn't get rid of them).
