Twiends is my favorite tool to increase Twitter followers. It features your profile several times, so more users find and follow you. Last week, I bought one of their premium packs to add featured displays, which helped me gain around 200 followers in 3-4 days. Review collected by and hosted on G2.com.

I didn't find any serious drawbacks. It is a good choice for Twitter marketers to improve their content visibility and expand audience. Review collected by and hosted on G2.com.
