I like that they are always there for you when it comes to questions or concerns about your project, their team is very knowledgeable in what they do! They also have great customer service which makes me feel comfortable with them as my development partner through out this process of building our app from scratch (which was awesome!). Nothing really at all but just make sure everything goes smoothly because if anything does go wrong then its hard to get things back up again once we're done developing so be prepared for some bumps along the way :) We had been working closely together over email/phone calls throughout most parts of the buildout phase where issues were addressed quickly & professionally by both parties involved - nothing bad here!!
