Well I Picked up for the first time from a person what was supposed to be 5 Grams, We all know normally the price ranges from 10-20 Dependent on a lot of things with the bud. Well i picked it up, My other person who was reliable, has seemed to have vanished, **That was just a side note** Anyway, Brought it back to my house, And I am very OCD, And can usually tell just from looking at it if its the right weight or not. But as said before, I have to weigh it for myself. Anyway, This Weigher has never failed me before, But the weed looked at least 3 - 4 Grams ( 1 - 2 less then i was supposed to get ), But My Scale Just stays on 0, Is there a reason for this?? I put something else on weighed fine, And there's no way its less then 1 gram. (Put 2 Bags Together supposed to be 6.5 All together, + The Bags, And still 0. Any Suggestions or Information??
