if you get one make sure you get a Current Shunt with it otherwise you wont be able to use your meter properly.
the only downside other than the bad calibration is that i didnt expect the blue LEDs to mess with my eyes so much. maybe if the digits where bigger it would be ok. perhaps its only because i am working with them indoors instead of outside in sunlight where the blue wouldnt seem as bright. isnt that funny how certain colors can irritate your eyes?
