I have no issues with install but it is always on my clunker laptop first, which is what I use to keep service manuals and work data for use in the shop.
I follow IT data scans on any software that is loaded on my system trusted source or not. But then I do not use Google or Chrome simply do to data tracking.
But even the most trusted company US, Korea, or elsewhere has had issues at one time or other.

Also the data output is there with or with out installing there provided software, so if you have any programing savvy you can record the data with out installing their provided stuff.

Aside from that yes you can get the same meter to some extent with out the Opto-isolated USB port from HF or EBAY. And if you find no use in your case of the data logging and visual display then buy the cheaper unit.
But after testing this meter its data logging for every meter function (temp, spark, dwell, volts, amps, etc.) is showing to be handy on observing condition changes.

I am very happy with its use.
