If the product works well. I have not tested usb3, just usb2, so inevitably we associated performance.
I've been running the machine write for several hours and I have not noticed heating: test with appropriate software in any case the envelope remains at room temperature.
The software is a bit special, but it works.
Just a minor complaint, go: the operation indicator is a bit lousy, it was the lighting of the led a little loose, but then I quibble!
I am very satisfied!
