See for yourself by reading reviews on the most popular resources:
Besides being a great product Support is Outstanding Besides being a great product, I would like to express how good the support is.I worked with Sam for over an hour, He went way above and beyond helping me with my Zapier Integration. Most companies would have just said that is "out of scope" Or "not my problem" Not these guys, they logged into my computer and dove deep into it and fixed my problem. Also keep in mind, I am only on a basic plan and they treated me like I was spending $1000's of dollars with them.

Great tool in a pinch! The google chrome extension worked really well since you can't just click on something in drive and easily open it - and I've had issues with Adobe for some time. This software did what I needed it to do multiple times. This is typically slow to open, and saving & retrieving files is a bit clunky.

The site was a little bit slow The site was a little bit slow, but it had tons of useful features, and I found the user interface much more intuitive than Adobe reader. I'd recommend it to anyone.

The system was quite user-friendly, however the quality of the initial edited documents was poor, with a green tinge appearing behind the altered text. A note to Paul at customer service had a solution identified, which solved the problem.

Kara provided great tech assistance and… Kara provided great tech assistance and she was polite, friendly, knowledgeable, and patient. The 4 stars is for Kara. The company on the other hand... not so helpful. They are great at marketing their product but provide very limited and nearly useless resources for helping their subscribers troubleshoot issues and/or educating the consumer on the tools and functions of the product. The company YouTube channel spends about 30 seconds on "how to" and the remainder of the video is promoting the product. Seriously, every single video, watch for yourself. All fluff and no substance.
