I don’t blame fasttech. They’re only the distributor. & They are always good with customer service.
I just think that 5avape is pretentious with their price point.
I remember the YFTK clone of the SVA bf with DNA 75 for 90$: that was a good deal and a well made mod.
I remember the 5avape stratum clone with yihi chip at 150$: that was excessive and a crapy-mushy mod.

I don’t use those anymore but my 5avape stratum balance is still good and cost 45$, honest price I think.

I also buy originals: sometimes it’s worth it, sometimes not.
