Hi,
I have ordered my first tinysa from kkmoon on Amazon some days ago.
I cannot remember if they were already negative customer reviews. If they were there, I did not read them.
at christmas wednesday, the "Spertrum Anayzer" arrived. I started the self-test, like described in the wiki, and test 7,8 and one other failed.
I made some photos and arranged to send the crap back with refund.
regarding kkmoon: I have ordered other electronic parts in the past, never had a problem.?
After receiving my money refund, I will add a fat customer review.
Dennis
