  • Good but not fast write speed

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Reading from this drive is pretty quick, as they promote. However, I found it be quite slow at writing. Nothing like you'd expect, since they claim similar read & write speeds. In fact, the measured speeds were in the USB 1.1 range (11mbps or lower). Poor for a USB 3.0 drive or even a USB 2.0 drive. This result has been consistent through many copies.

  • Best speakers at a low price.

    These T-50 speakers are as good as the Model 60 that are pricier. The bass is thunderous with NO crackling noise (thanks to the two passive bass speakers). The mid range sound is perfect for solo voice and the high (tweeter speaker) sound is really high with no distortion. The case is OK, and the speaker has regular looking grille, but the overall design is real good.
