I like that it is easy to use, has great customer support (both live chat & in-app), offers free trial period so you can try out their features without any risk of losing your investment or data! Nothing at this time but everything seems very solid from my experience with them thus far.
We're using git colin for our project management team as we are building an online platform which helps teams collaborate through software development projects - both frontend/back end coding etc., This allows us all to be working together seamlessly across different devices and also have visibility into each others progress throughout every stage of product creation.
