Software snafu for this clone, hardware V2_2 Time Owned: 0 to 3 months.
I have owned a NanoVNA for a year and it's a fine device except for the tiny screen. When I came across the SAA-2N with its 4 inch screen I bought one from randl.com. On initial test it had poor S21 magnitude accuracy, the readings had over 3 dB error. Thinking it might be a firmware problem I tried updating the SAA-2N. There were 7 versions of the software and no hint which to use so I made a wrong guess and locked it up, nothing but a blank white screen. A call to randl.com was no help but they did offer a full refund.

Finally got the correct firmware (Blackmagic V2.74) loaded and the accuracy is now within 1 dB over a 70dB range. It remembers the calibration factors on power up and the menu operation is nearly identical to that of my NanoVNA. Five stars+ for the SAA-2N performance after the update. And, the 4" screen is a big improvement.

Buyer beware that there are many clones and little data so firmware updates can be confusing, hence the 4 stars.

Not that Great Time Owned: 0 to 3 months.
Not that great, even with a stylus the display is difficult to deal with (even after doing the display touch calibration)
can be very frustrating at times. Tends to hang up after a Normalization IE Load, short, open cal.
Needs to have a turn on default ability so you can keep the preferred display orientation and settings the same at turn on, takes time to go around and reset everything the way you want it over and over again.
Don't even get me started with the desk top software, talk about error after error.
Once you get everything setup and caled it is accurate for the cost and size but....
Most if not all of these NanoVNA's are the same. Save your money and buy a better analyzer in the $300-$1000 range.
These are just a toy IMHO
