Test it out. Buy one of those brooms for a friend and then after s/he's had it for a week, if s/he's gibbering about invisible cold-skinned thingies that crawl into the bed with him/her and demonic voices that periodically say strange things like, "Kill, kill, watch Judge Judy, kill, kill" then you might want to avoid them. However, if s/he doesn't, they might be okay to buy.
