I use drawboard pdf on a near daily basis to markup documents, and for notetaking. I have been using it since it first was introduced and have been extremely happy with it. I recently had a problem with drawboard freezing intermittently after an operating system update. I contacted drawboard support. They were courteous and quick. They had the problem resolved within a couple of days. I am a very happy customer. Review collected by and hosted on G2.com.

No downsides. Everything is great and the product is constantly improving. Review collected by and hosted on G2.com.
