Ultra Fit USB 3.0: Excessive Heat

I have just ordered a few of these (in total I have approx 8 of these USB3 32GB and 64 GB)

They were selling cheap.

I too noticed excess heat.

Does anyone have a link to an official Sandisk posting, saying that we do not have to worry about data loss ?

I can live with burnt fingers, as long as I do not risk losing data already stored on them

Potential loss of data could have me jumping off a cliff (as a Scot would be bereft if he thought he could lose data after all of those purchases)
