I was brought up on the old Robin separates and liked the "set the scale & hit the orange button" simplicity which has been carried on by Kewtech since Fluke took Robin over. I've had quite a bit of experience of other testers since & I found the Fluke multi-function tester a bit over complicated, the new Megger MFT testers however seem a lot more intuitive to use than the Fluke & I've been impressed. I know other people who would argue the opposite though!
