Rated 5 out of 5 by from Excellent, simple tester Great value tester, build quality feels good. Includes phase rotation which is a bonus and the torch is really handy for inside disboards. Glad I upgraded from the rubbish I had before.

Rated 5 out of 5 by from Electrician Reviewer The kewtech tester is great it has a torch which is good for times when power has turned off and you need some light , so very useful. The actual tester itself has a good audible tone which helps to clearly hear when you are testing. It also has leads that are fairly long so you wouldn't be out of reach for your testing tasks( except if it's really long distance testing lol).

Rated 5 out of 5 by from Great tester Materials are good quality and buzzer and clear light indication is very good. I thought the extra touch of an LED torch might be a bit of a gimmick but it's really useful especially when working in poor lit area's. Price was Would definitely recommend. "
