Also used for watching videos on Philips and LG TV.
I ordered 2 and they work perfectly.
The design is terrible, for me they are the finest in the market.
By cons they are very small, it can be an advantage as a disadvantage. For large fingers, it's not always easy to handle. And out of the USB port on the TV, not obvious.
The "gold-plated" is also inserted into the USB socket, so the end is a little scratch, and it rubs a little more.
I would advise rather for entertainment, and if aesthetics account. For the office, choose a larger and more ergonomic.
