    I love this tester - I purchased it as it was cheaper to buy new then repair my old Megger. It's so easy to use and also very light weight. The leads are good and I received good service in order to get my tester delivered next day. Much receommended
    Review by Lionel RichTea (Posted on 24/09/2013)
    Ordered one of these a few months ago as price is good. Its not clear where test leads are plugged into tester and my results vary substantially. I like its ease of use but other than that I wouldnt recommend. I did like the service from test-meter, just under 12 hours from ordering to delivery which was good and I got an hours time slot for delivery too.
