Review on 🔌 Sperry Instruments VD7504GFI: DualCheck Non-Contact Voltage Detector + GFCI Outlet Circuit Analyzer with Visual & Audible Indicators, 50-1000V AC, 250 lb. Crush Rating by Brandon Patterson

This is an attractive tool and seems to work well in the limited range of tests I have used. Number 1. It should come with printed documentation, not with the silly excuse that it's green. If you want to be green, don't use plastic packaging.2. The attached note says that there is no battery, but the battery is included and easy to lose when unpacking.3. The specified battery is LR44. It comes with a different battery that works but is confusing.4. The battery cover requires a very small Phillips tip. It must have a latch.5. Supervision is required to read the battery installation chart.
