Tim, Deepcore, and some other members: the feedback i get here on tfl is more or less the same as the local view of these kinds of electronic scales.
some guys goes go through all kinds of rituals before they start loading. a local reloader e-mailed me list of about 17 things he makes sure of before he starts weighing. these scales seem temperamental. no self respecting reloader will take this kind on grief from a balance scale.
it is my opinion that the technology that one need to affordable manufacture these kinds of scales doesn't yet exist.
