Query: Too much $$ for too little help

Although I could get this little gizmo to work sometimes, it is quirky and, over the long haul, not worth the trouble. Once a stamp gets lodged in the mechanism, which can happen pretty quickly, everything is knocked off and it ceases to work properly. It relies on stamps being perforated to an exquisite level of perfection and cut exactly straight. Of course, they hardly ever are, so stamps get jammed. Save your money.
