We have been using this for years now, it's like having two companies to do marketing when one will be able solve both issues at once! I feel really comfortable with them since they understand our business model perfectly after working together closely in 2 previous projects we had done as well (I'm not going into detail about that here). It took us some time initially but then things started falling back from there thanks partly due their support team who helped out so much during those initial days of integration process - no stress or headaches ever encountered by me throughtout my entire relationship thus far!! Highly recommended if you are looking up an option where your data synchronization needs can get taken care off easily without any hassles whatsoever. Nothing major yet apart form minor glitches which were rectified right away within 24-48 hours max. They offer multiple plans depending upon how many users u need to integrate along.
