The program allows you to see at all times what competitors are doing in order to adapt your own marketing plan accordingly; it has an excellent UI that makes things easy & very intuitive! It's not perfect - there can be some problems with certain browsers (such as chrome) but we've found solutions using other programs/browsers which have helped us get along without any issues so far.
I would recommend this product if one needs good insights into their competition AND they're looking something different than traditional B2C or CPG companies who do mostly e-commerce sales online. We use ur looker mainly just because its free, simple yet powerful tool (the data sources available here allow me to monitor my market pretty well).
