I have recently bought the MTM digital scales and am not impressed, to be honest.
Seems to jump .2 grain very quickly rather than smoothly through .1 at a time and need to re-zero regularly with the 50g weight as it is out all the time, only by a small fraction, but I am a bit anal about these precision things.
My friends accuse me of having OCD, but I disagree. Anyway I need to spend about an hour now checking the grammar spelling etc of this post or it will bother me all night!
Cheers
