Easy to use for both internal and external users. The mobile app is a great feature. The interface is simple and easy to use, which is great since we are a small company. Very helpful for our small team. It is a great tool for us to use. Not much that I dislike. I would recommend this product to anyone looking for a simple way to communicate, share information, and collaborate. We are able to easily communicate with our team members and our clients. It is also great for our clients to be able to communicate with us.
