"Fantastic sound for such a transportable speaker"5.0 starson by pmignini
Pros: Light, relatively portable. Fairly sturdy. Fuller sound than other battery-powered or rechargeable units. Simple, functional design.
Cons: Minor: rubber cover over power cord input is a pain to open.
Summary: Bought this unit for my daughter about a year ago. I've been using it for months, and love the sound. Battery is fairly durable. I get about 4-5 hours on highest volume, longer at more moderate volumes. Has a far fuller, richer sound than other portables I've had, including other Logitechs. While I agree with Cnet that a clock or FM would have been nice, the unit as-is is probably the best in its class.
I'd add that I write this after using this while chaperoning a week-long field trip with a high school, and had this perched on the dashboard of our bus. It's hit the ground a number of times and is still fine, thus, its a quality build.
