The ease of creating profiles, the ability to upload multiple files (documents, videos), the customer support, the ease in searching profiles/services, etc are all great! I do not have any dislikes about SERV at this time but if there were anything it would be more of an enhancement than something else.
If you're thinking about using SERV please give them a try-it will not disappoint! We use SERV primarily as our marketing tool by providing opportunities for customers to engage with us through various channels including social media.
