Review: Not reliable - Inconsistent, sluggish response, unreliable sensing voltage presence Review: Simple to use and doesn't require extra batteries - Great value for the price but very small display. Needed something for a single job of replacing some GFCI's, and this one did the trick. I can confirm that this works for both AC and DC. My only problem was the display which shows a little lightning bolt - it is tiny and need some good lighting to see. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000646OGY | | Best Sellers Rank | #359,923 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #281 in Voltage Testers | | Brand | Sinometer | | Brand Name | Sinometer | | Color | Black | | Customer Reviews | 3.2 out of 5 stars 86 Reviews | | Item Dimensions | 5.7 x 2.8 x 1.7 inches | | Item Weight | 0.15 Ounces | | Item dimensions L x W x H | 5.7 x 2.8 x 1.7 inches | | Manufacturer | Sinometer | | Measurement Type | Voltmeter | | Model | DCY25 | | Part Number | DCY25 | | Power Source | Battery Powered | | Style | Handheld | | Style Name | Handheld | | UPC | 639429004971 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Sinometer - **Power Source:** Battery Powered - **Style:** Handheld - **Color:** Black - **Item Weight:** 0.15 Ounces ## Images ![DC & AC Non-contact Voltage Detector, DCY25 - Image 1](https://m.media-amazon.com/images/I/51V650PiIjL.jpg) ![DC & AC Non-contact Voltage Detector, DCY25 - Image 2](https://m.media-amazon.com/images/I/41BUZmxWO-L.jpg) ![DC & AC Non-contact Voltage Detector, DCY25 - Image 3](https://m.media-amazon.com/images/I/4198MHKOpHL.jpg) ![DC & AC Non-contact Voltage Detector, DCY25 - Image 4](https://m.media-amazon.com/images/I/61sSNKJbXsL.jpg) ## Customer Reviews ### ⭐ Not reliable *by D***1 on February 2, 2023* Inconsistent, sluggish response, unreliable sensing voltage presence ### ⭐⭐⭐⭐⭐ Simple to use and doesn't require extra batteries *by M***P on April 24, 2021* Great value for the price but very small display. Needed something for a single job of replacing some GFCI's, and this one did the trick. I can confirm that this works for both AC and DC. My only problem was the display which shows a little lightning bolt - it is tiny and need some good lighting to see. ### ⭐⭐⭐ It worked. *by M***E on August 3, 2018* It works. Would not use it on something of very much importance, though. Screen in picture description is misleading. It is very, very small! Needed a cheap tool for an easy, fast fix, and it did it's job. --- ## 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.co.uk/products/12845599-dc-and-ac-non-contact-voltage-detector-dcy25](https://www.desertcart.co.uk/products/12845599-dc-and-ac-non-contact-voltage-detector-dcy25) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-23*
