It was only $5 to get both the non-contact voltage tester and the contact voltage tester together, so I figured I might as well. The NCVT is great. It has two modes, a high sensitivity mode that can detect voltage as low as 12VAC, and a lower sensitivity mode that needs at least 70V to be detected. This later mode is useful in certain situations. For instance, the 12-1000V mode will pick up noise from cables that obviously don't have AC voltage, such as USB cables; switching to 70-1000V mode will ignore the signal from the USB cable. The flashlight is a nice extra, and it operates separately from the voltage detection. It's waterproof and dustproof and uses ordinary AAA batteries, which can be replaced just by unscrewing the end cap, no tools required. I'm not really sure what I would use the contact voltage tester for. It can detect DC voltage, but only at 36V or higher, far beyond anything I normally use. It also can only detect 4 levels of voltage: 24, 48, 120, and 240V AC and 32, 64, 160, and 330V DC, but there's nothing showing if the voltage is in between. It also doesn't appear to indicate whether the voltage is AC or DC; it will display 3 lights no matter whether it's 120VAC or 160VDC. But for only an extra $5, it's not a bad little tool for quickly checking a receptacle, and you can mount the probes so that you can test outlets with one hand.
