1 reason NOT to buy the Dynabook Tecra A40-J

1. Speakers

The laptop has its speakers on the bottom, which isn’t that bad, because thanks to the little rubber feet, the sound bounces off of the surface on which it’s placed, and still comes to your ears relatively uninterrupted. In terms of the quality, there are deviations across the entire frequency range. Furthermore, the high tones are overexposed, while the mids and lows are muffled. There is also a lack of bass.
