The transfer rates are really fast USB 3.0, no long with lubricated more, especially that the stick has exceed the manufacturer's instructions I was positively surprised. When writing it reaches speeds of 40-45 MB / s when reading and a little more than the stated 90MB / s.
A small LED indicates the operation status when the stick is plugged in and the sliding shutter is also good.
Sometimes you have to hold this, but frankly no demolition and I hold the thing when pushing anyway.
Is not super complicated or difficult it to plug in any case.
The case seems durable and I think can be thrown easily to transport in the pocket.
Just buy it, never again slower memory sticks.
