We have been using it since 2016 when we switched over from another system (which had some issues). It has worked flawlessly ever sense! There are no complaints here at all so far as I can see. The best part about this program is that you don't need any training or help - once setup correctly with your tap lines everything just works great!! You will be amazed how easy this product makes keeping track of our beer line up in an organized fashion very simple. Nothing really but if there's anything specific they should do more research into before implementing something like this because most things work well enough without needing too much thought put behind them by someone out-of-the box thinking. Keeping everyone informed what exactly where each barcode stands helps people who may not know quite understand why certain bottles/cans aren't showing after being served yet still show up later down the road.
