Reasonable but not fantastic Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it. The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use. Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.
