I like how easy it is setup with any SaaS platform such as Salesforce CRM etc., no need of installing modules in your system! The tool also works well even when you have less than 10 users within same organization since its completely automated process which makes sure that there are not too many issues during roll out phase (it's pretty good!).
You can't use this product if only few people using airCloaks at one time because their performance will be very slow compared other tools available but overall i think so far nothing much dislikes about them :) We used Aircloak Insight mainly from our sales team perspective where we create reports related information regarding new leads/prospects who has been added recently by different reps & clients info alongwith current status they're working currently - all these things helps us easily track progress made towards each prospect individually without.
