I love how easy it was to set up with our existing point of sale hardware (cash registers). We have been able use this product since we started using cash register systems over 10 years ago! The only thing that has come out lately are some minor updates but they haven't really changed anything too drastically from what you would expect when setting something like provectorapos - so no complaints there as far as functionality goes :) There's nothing about proofectorpos itself which isn’t great or useful at all; however if your looking into purchasing new Point Of Sale Hardware then make sure compatibility issues aren‘e checked first because otherwise everything will work perfectly fine once installed/setup!
