KewbzUK review for Simprosys Google Shopping Feed

Ruined my current GMC and google ad setup. Had a 1100% ROAS running my ads manually. Installed this and was told it wouldn't affect my current setup. With a few days my ROAS is now <500%. Products have been adjusted in my data source and was assured this wouldnt happen. Confusing app, useless support that was slightly rude and abrupt but maybe that was a language barrier so i wouldn't say that was too much of an issue. However, the drop in my ROAS is the main issue for steering clear.
