It says "Klein" on it, so you know it works and you don't have to replace it several times a year. Just buy it.
If you need a gripe, it doesn't have alternating tones on the tone generator box or have a headphone jack on the wand like some other toner kits do, but it's still a Klein and I'm a tool snob when it comes to quality, so I bought it anyhow.
