Emis provides extensive coverage of developing economies across several sectors such as trade & finance (including commodity pricing), banking sector activities to retail market access etc which is very helpful while doing my MBA dissertation work.
As far I understand there isn't much that can be disliked about this excellent service provider so if your looking out for quality services go ahead and use it! Nothing specific at all but overall experience was good enough!! Good choice when searching online or offline sources especially if one has limited budgets available during their study period.
