Good price for a well known brand beating its last deal by a buck. 10w speaker. 3.5mm jack.
4.2/5 star review at Amazon. Static has these from $16.95 to $25.
Note that this is not a bluetooth portable speaker. It has no volume control. Requires an external power supply (included).
Possible price match via OfficeWorks
CNET review 3/5

The good The Logitech Z50 plays loud for its compact size, is simple to set up and use, and takes up very little room on a desk. Best of all, it only costs around $20 and works with nearly every device.
The bad No battery or wireless option; the exposed speaker driver might get damaged if something is dropped on it; bass is light and the speaker can distort at higher volumes.
The bottom line The Logitech Z50 is about as no-frills as you get for a multimedia speaker, but at $20 it's not a bad deal for the sound it delivers.
