I admit, I was maybe a little bit hard towards the yihi stratum’s style. Because mine stopped working and I hated the fire button. My bad feelings came from my personal bad experience with the mod. I did like the form factor a lot but maybe a little slippery and sloppy.
And the other famous shop did not refund me. I don’t personally like Yihi and I don’t know if it was a faulty chip or bad soldering but it was my first and last.
I had a bad experience with an original Stratum also, yeah lucky guy. But Stratum refunded me.
By the way I don’t think Stratum still use Yihi anymore. Last ones I saw were DNA60 or Dicodes.
