I like how simple it is to set up in my browser of choice (Chrome).
It's also very easy to use when testing websites from within Google Docs or other applications such as Slack/Teams etc. The only thing i dislike about this tool is its price tag - $20 per month seems steep! You get what you pay for with checkbots support team not always being able to help out quickly enough which leads me back to using free tools but then there are no alerts if something goes wrong so have to rely solely on user feedback. We're solving our website accessibility issues by ensuring we follow WCAG 2 AA guidelines across all pages of our sites.
