This product is well-designed, with an efficient and quiet fan, comfortable padding, and good sound quality. The only drawback is its weight, while contributing to its stability, makes the unit cumbersome, and might limit its usability under some circumstances. Before purchasing, you should consider its size -- the padded rests on both sides are substantial and the unit could easily fill the distance between the armrests on a coach flight or your favorite chair. I was pleased with the sound quality - good mid and bass response, quite an upgrade from the soft and tinny sound from my Macbook's internal speakers. Of note; the USB connector cord is built-in, with a finite length. You cannot readily substitute a longer generic cord. This should not be much of a problem. Finally, when sitting on my couch, with my Macbook opened fully, I sometimes cannot get the best angle for viewing the screen. A squirm sometimes cures that, but again, it's something to consider, depending on how far your laptop opens, screen viewing offset, etc. Logitech designs and builds quality products, and this is no exception. It is solid, with excellent fit and finish of all components. If the size, weight, and viewing angle issues are not problems for you, the improved sound, unit cooling, and comfort make for a good upgrade alternative to the \"fan-only\" type of unit. PROS: Good cooling, silent fan, good sound quality, solid construction, well-designed and built. CONS: Weight and size
Output:
Works quite well, but a bit heavy
