I bought this barcode scanner for my mini shop operations and it is of great help. I scan all products without a driver installation or any kind of special software and the number shows on the screen. I am sticking with the iBall WBS-650MV 2.4GHZ Wireless High-Speed 1D Barcode Scanner Reader Grey scanner because it has a flexible working distance of up to 100 meters. My customers tend to spill vapor from their cold drinks on my cash-in table as they make payments for their items, but the water droplets do not interrupt my scanner operations because of its water proof nature. Above all, this bar code scanner is easy to handle given its light weight and a strong body.iBall WBS-650MV 2.4GHZ Wireless High-Speed 1D Barcode Scanner Reader
