ya same here i have a metal one that i got for 4 dollas new but even if i dident have one i still wouldent get ripped because i can eye the bag and see if it a 8th, Quarter, but when it gets to ounces and over that i buts out my dealers digi or his scale if i dont have one on me and i weigh a nickel (i litteraly mean a nickel money wise) on it and if it weighs out to 5 grams the scale is stright. just so ya no a nickel weighs any where from 4.85-5.15Grams. and yes when i only have so much money i do buy a joint or a dime
