The issue is when you try to set up the client. Oops, typo in something, let’s try again. Oops, forgot to set permissions. Again. Oops, forgot a domain. Oops, forgot to sudo it this time. Oops, limit run out.

I’ve been through that, now I just use https://gethttpsforfree.com/, which avoids the issues.

And it doesn’t wreck my Apache config every time.
