    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.

    Good so far, the only thing I don’t like is when there are some offers and other things already on it taking up space. It advertises 128 GB space but in reality it only offered 114GB. They can be easily erased/ deleted to free up the rest of space to actually have the entire worth of 128GB. Good all-in-all.

    Picked this up on sale, hoping to use it with a gaming console. It didn't work for that, but works great for everything else. This will replace a 32GB drive I used to carry with me for quite a few tasks. Worth it to me as I can carry several larger files on this without too much trouble. The USB 3 speeds mean that it will work well with my newer machines for faster file transfers.
