This Twitter module works good at what it does, but is missing some features that many other modules have.
I got Latesttweets because it is the only 3.2 compatible twitter module that will display tweets from multiple twitter accounts. This feature works well, and is simple to set up.
What is missing are options to customize the look, such displaying the avatar or not, choosing between displaying the twitter username or real name etc.
This would be worth the $$ if it had all the options that the free modules have, plus the ability to display multiple feeds. Responsive would be nice too.
