Review on KAIWEETS Dual Range AC Voltage Tester/Non-Contact Wire Breakpoint Finder - Live/Null Wire Electrical Tester with LCD Display (Orange) by Jeremy Hong

I had several non-contact voltage testers in the form of a pen. I use them primarily to make sure I don't have a live wire when breaking into an outlet or electrical box, or touching the end of a cord that someone else says is off by a switch. This is mainly to make sure I don't grab a live wire before I get electrocuted. They are all generally lightweight and tend to break fairly easily when hit in a tool bag. So I don't go for the most expensive ones or the ones that have more features than I really need. In the case of the Kaiweets voltage tester, it seemed to fall into a unique golden mean; It was affordable, seemed well made, and easy to use. I liked that it had an on and off switch. Many other brands have a pivoting end that also doubles as access to the battery compartment, where you sometimes accidentally open the batteries instead of turning them on or off. The Kaiweets tester will also turn itself off automatically if you forget, so you don't have to use it and find out that its batteries are dead. It's fairly simple, with both an indicator light and a beep when current is detected, and it gives you an approximate voltage level when you put it on a circuit. And unlike many of them, it will let you know when the batteries are low, so you won't know if you're trying to use it in the middle of a job. It works? Yes. Will it last forever? no It's $12. If you want high quality, pay more for one. Will it cover the needs of a weekend warrior doing home renovations? Yes it will.
