First off, I'm a little high. I know, but it's a rare thing for me to be on grasscity under the influence. Basically me and a friend are looking on ebay for another toking tool. It's one which I have come to see as yet another essential to our daily addiction: a grinder! Problem is, he's looking at this battery operated one (batteries are not a problem) which can ALMOST powderize weed... pulverizes. It's at a good price....i think $25 which ain't tooooo bad. But should I just get a good old fashioned metal grinder for twenty? I'm just worried the weed the other will spit out will be too much like pure' if you will (powdery). Any experience with such a battery-operated device? How well does it work?
