Good price. Good value. It's what I need to replace existing light pole outside with which I need to insulate some existing wiring while I install solar-powered lighting. I want to make sure the old light is completely de-powered before messing with it. ### ⭐⭐⭐⭐⭐ Two great tools in one package! *by on Reviewed in the United States May 10, 2020* We are updating our home. If you are doing any DIY electrical work (we changed out our light switches to rockers and newer wall outlets/receptacles), these two items are necessities! A must have. Always turn off the power at the breaker box BEFORE doing any work with electrical wiring. The Sperry volt meter is accurate. Isn't over sensitive (some reviews mentioned) but can be a bit tricky to use around walls with multiple power connections. Otherwise, its worked great for me. Especially when I've had individual wires in a junction box to check. The Sperry outlet tester is perfect! Easy to use and the visual confirmation lights are fantastic. It can, also, test you GFCI outlet with push of a button. Simple. The Volt meter takes one AAA battery (this is the only negative in my opinion) and the outlet tester is good to go out of the box. Happy DIY! BE SAFE. ### ⭐⭐⭐⭐ Nice Voltage Indicator - Not a circuit tracer! *by on Reviewed in the United States August 19, 2025* This is a nice Voltage tester and GFI outlet tester. It is quite sensitive to electrical such that you just need to get close to outlet breaker before it starts beeping. Be careful when using in gang boxes where you might get a false reading when you have a live switch next to a non-live switch. It functions well and is lightweight and easy to carry. It quickly identifies voltage and the battery will last a long time. The led is bright and its obvious when lit.THIS IS NOT A CIRCUT TRACER. That is, this will not indicate which breaker controls the circuit that the adapter is plugged into. This unit only indicated the presence of voltage. ## Frequently Bought Together - Sperry Instruments STK001 Non-Contact Voltage Tester (VD6504) & GFCI Outlet / Receptacle Tester (GFI6302) Kit, Electrical AC Voltage Detector, Yellow & Black - WGGE WG-015 Professional 8-inch Wire Stripper/wire crimping tool, Wire Cutter, Wire Crimper, Cable Stripper, Wiring Tools and Multi-Function Hand Tool. - 180 PCS Wire Connectors, Insulating Insert Twist Electrical Wire Connectors with Spring, Portable Wire Caps for Quick Connection, Colorful Wire Caps Electrical --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/8473068-instruments-stk001-non-contact-voltage-tester-vd6504-and-gfci-outlet](https://www.desertcart.jp/products/8473068-instruments-stk001-non-contact-voltage-tester-vd6504-and-gfci-outlet) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-17*
