Review on Cassida 5520 UV/MG - High-Speed Money Counter With ValuCount, UV/MG/IR Counterfeit Detection, Add And Batch Modes - Large LCD Display & 1,300 Notes/Minute Counting Speed - Ideal For US Currency by Derek Wagner

Make sure you read the "Use Manual" before use, especially the troubleshooting portion. This will alleviate unnecessary errors when you encounter a miss feed or issue with a double feed.I put the machine through its paces the day I opened it. The machine will startle you initially when you load the bills into the hopper, because it starts counting immediately. It takes about one to two seconds to count 20 bills. The batch mode is great if you need a specific number of bills in a stack (e.g. needing stacks of five bills out of a consolidated stack of 38 bills). The machine will also add the value of a stack of denominations.The only "down-side" I found is that the stacks to be fed through have to be the same denomination. It does not recognize multiple denominations (e.g. a $5 bill in a stack of $20 bills). But if that is what you are looking for, you probably have a much larger cash flow than most small businesses.
