Great product. Easy to install. Gave me hours more viewing for my TV. This product improved watching HD programs with my new Samsung HDTV.
Good Review

This is our favorite of many items we've bought from Anker. We love having the wall charger, retractable cable, light weight, and small size.
Good Review

This one sucked big time. From it's title "Corporate Secrets...", i thought it would help me understand more about corporate communication strategies of my bosses as they relate to my own workplace. Well a quick glance at the content wasn't enough to know that not every single advice offered here contradicts another.

Bad review
