I like it. Freed up memory from some pre-loaded apps and optimized speed. Also stops viruses from FB and other social sites. $2.99 per month and added to ATT bill, which is smaller than all the taxes ATT adds. Stops eavesdropping and has other features I like. You can cancel at any time, and icon on my home screen allows one touch, bam, phone optimized. Many tools I haven't explored, but so far I am very pleased.
