I like that it's very easy to use, you just plug in your meter into computer via USB port and run software-and voila! You have all kind of features available right at hand which makes my job easier when calibrating various test setups with different instruments (from low cost ones up tp high end). It is not so customizable but this can be easily fixed by adding 3rd party addons/plugins if needed. So far no problems or dislike about metbench itself however there are some limitations regarding number of modules. If you need something more advanced than basic setup options provided then go ahead as long as MetBench works fine out of box otherwise maybe try other tools first? We used it mainly because we wanted reliable calibration solution without having to rely too much on instrument manufacturer support.
