No problems, good price, good quality. ### ⭐⭐⭐⭐⭐ Best hot stick value that works *by A***R on November 26, 2025* I looked at several and watched a lot of reviews. This is the best bang for your buck and works great. Fits inside the front of a GFCI too. Very happy with this hot stick. ### ⭐⭐⭐⭐⭐ Much more sensitive than other devices. Just what I was looking for. Has an ok light. *by M***R on January 3, 2025* Great unit. 5 stars. Very sensitive. It can give some short false postives but I am totally fine with that. I would rather have little short beeps than a false negative. (A false negative means there is no beep when there is voltage) If given the choice between really sensitive and not sensitive enough, I want really sensitive every time. The false postives are short little chirps and the real positives are a long string of beeps and lights flashing red. If you tap the tip on certain things you can force a very short false positive. (just like my beloved old unit) With this Southwire tester I can touch it to light switches and get an alarm. (with the cover on) Of course be careful and always test the wire before you work but I like the ability to sense from a distance too. Also test the unit to make sure it is working each time you use it. Before I bought this, I bought another brand, which I perceived as a top brand, and I paid more money but it was nowhere near sensitive enough. This Southwire unit is perfect. The price is amazing. I have a large DC adapter with a flat 3 wire AC wire feeding it. It does not beep on one side but does in the middle or the other side. I can't even say it is overly sensitive. It is just about perfect. If I had a potentiometer to set the sensitivity, I would lock it in place right where it is at. I lost my old unit that I had for many years. After buying another product that didn't work for me, I found some YouTube videos with reviews and decided this was a good choice. The light is just ok. It is powered by 2xAA batteries and has an LED. It is bright enough that you don't want it in your eyes. (you will see spots, don't ask me how I know this) The light is adequate for looking at wires in a box. That is just a bonus for me though. I have lots of bright flashlights. To power on the light, hold the red button on the end. To power on the unit for detecting voltage, hold the red button near the tip for a second or so. The tip will glow green while it is on. It flashes red and beeps when voltage is detected. (fairly loud) It can be turned off by single pressing the power button or you can let it time out. (a few minutes) It makes a different beeping sound when it turns off either way. So far I only wish that I had bought two of these. (keep one in a known safe place and use the other one) I believe I like it better than the one I lost. ## Frequently Bought Together - Southwire Tools 40116N NCV Detector 100-600V AC - Southwire 40022S Receptacle Tester; Black - Southwire 40150N Advanced AC Non Contact Voltage Tester Pen; Dual Range 12-1000VAC/100-1000VAC; Non Contact Voltage Detector with LED Flashlight; 6' drop test rated; and IP67 waterproof; NCVT --- ## 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.ph/products/55208956-southwire-tester-ncvd-detects-ac-voltage-with-audible-and-visual](https://www.desertcart.ph/products/55208956-southwire-tester-ncvd-detects-ac-voltage-with-audible-and-visual) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-22*
