I had high hopes for this plugin - the interface is easy for my clients to work with, and it is simple to integrate.
However, it is buggy - I quickly ended up with an error on a page - and there are certain obvious styling is not present (like removing days of the week when no classes are listed in list view.)
I reached out to support - by email via their website, through the forums, via their website again - NOTHING. Not a word.
As Spence says in his earlier review, "Support for a plug-in is as important as the plug-in itself." I agree wholeheartedly - because if we install and like, we then RELY on things. I am grateful the error showed up BEFORE we took the site live, not after - or else I'd really look bad in front of my client.
I'd give it two stars if I wasn't so frustrated with this experience - but it gets one star because throwing something out there without thinking about how to support it is exceptionally poor practice.
