Really handy device
Really good device and quality. Does exactly what it’s meant to do and has been handy on a few projects. Quality and build to last and I am sure it will hold up.

Great pocket mains detector
Great little pocket voltage detector, has 2 ranges for detecting lower voltages from 12vac up with more sensitivity or when you are trying to determine which wire in a group is live the 70vac up range gives less sensitivity, also has separate tip led colours depending on the range selected, also has a fairly bright flash light on the measuring end, so actually lights up what you are trying to work on/test, which is handy unlike on my last fluke tester which had the flashlight on the rear, so it was either a tester or flashlight, and not both which was pretty pointless. Have used it daily for the last few months and has been faultless, accurate, please do always check the wiring is actually off with a second meter to be 100% sure, this is the same with all voltage detectors.

Sturdy as hell
I had a fluke volt pen before this and I must say the fluke was less sensitive which is good and bad- but where as the fluke would constantly eject it’s battery, the Kline is sturdy, and nothing will fall out or get pressed accidentally. The kline is sensitive which is good as it tells you straight away if there is power anywhere near it. Isolating wires with it can be hard as even on the less sensitive setting it’s still able to pick up power within a couple centimetres of the tip. The important part is that it will keep you safe. And the light is excellent.

Good if pricey
Good tool, and really handy having a torch in my volt pen. Build is robust and it's hard to think of anything negative to say about it in itself. It does seem a little bit on the expensive side though.

Great tool. Replace the packaged battery.
This is my second one. The first was great to use, but the included battery leaked and ruined it. Despite that I bought another one which says how much I liked it.

Despite the slightly higher price tag, it's worth the money.
The incorporated torch is surprisingly bright and has proved to be a very useful on more than one occasion. The "no touch" volt tester is easy to use and feels robust in the hand.
