Good question. It’s a pretty lightweight hub and a nice tight fit, so I doubt the hub itself would cause problems in that regard. If you’ve got USB sticks in there all the time, or regularly have heavy cables or other accessories hanging down that don’t rest on the desk/table, maybe there could be an issue longer term, but it wouldn’t be a major concern I don’t think.

There’s no single answer for that — it really depends what your needs are.

I no longer have the hub to check with, but don’t recall it doing so during my testing.

Hmm, maybe so actually – I don’t remember if there was a problem trying to use it that way or not. I don’t have the adapter any more to check, unfortunately.
