there's just no way all these nickels weigh different amounts and even if they did there's no way some would be under 5 grams which would be necessary to cancel out those over 5 grams.. ugh I'm so fucked! I bought this thing like 3 weeks ago for 25 bucks and I used it ONE time for weighing out ONE ounce..now I take it out a few weeks later to weigh a SECOND ounce and it's completely ass-fucked?! I just don't get this.. I'm really waiting for that one person out there with the golden answer..
