Hi, I think I'll chime in with my Banggood experience. I did not
know about this group when I bought it, or the concerns about
copies and clones were so bad.?
It also did not come with a stylus.
I don't have any complaints about it, it works good.
I did ask the seller beforehand, if it was authentic, and capable
of being upgraded, because I saw their policy said "flashing
firmware voids your warranty."? I did do /some/ research first.
It is the ZS-406 model, and it can measure up to 12.072 GHz after
unlocking Ultra mode. Barely into the range I really want to
measure (Starlink). I guess they were liquidating their older
inventory, thus the sale price.
Now I wonder if ZS-407 can go higher, since the base frequency
range is up to 7.3 instead of 5.4, I wonder how that corresponds
to the Ultra range expansion, and how that compares to authentic
hardware. Which is newer? Can the cloners make more capable
hardware than the authentic version?
Thanks, Stewart

This is how looks tinysa ultra + from banggood. I dont have
any calibrated signal generator to test how to measures. Seller
says its genuine, i dont think so, there was no pen stylus
inside.
