I have been working with this team for 3 years now, they are very professional in their work but also friendly at all times! The support is great from start till finish as well when needed during rush hours or holidays etc., nothing that i dislike so far about them except maybe some minor problems here an there which were sorted out by our manager quickly without any complains coming forward.. we started using it few months back after looking into other solutions available online like DoubleClick/Adobe DFP platforms however found no value added features compared to optiMHAttribute hence decided go ahead tryout since its free trial offer was still going strong!!
