This is a premium product that offers a trial.

The fact it asked for permissions and access to my Trello including my email address etc. and then told me to sign up for the trial *afterwards* really left a sour taste in my mouth so I immediately removed the extension and revoked it's access to Trello via the Trello settings. Gaining permissions for access to my information before I actually sign up or get told a price just feels really sketchy to me.

I've given it 3 stars to give the quality of the extension itself the benefit of the doubt, and dropped some stars based on my initial experience.
