Depends on whether you use it for your livelihood or not.  :-DD

Aliexpress added to shit list. Just threw three hours down the shitter. This is TEA related as I found the old frequency counter I built years ago and am making a new front end for it as the old one had random impedance. Also need to stuff it in a new case.

So I’m using a 1mH axial inductor as part of a Pi filter to stop digital spikes getting into the front end.

Powered it up. Nothing. Hmm.

Poked around with DMM. No 5v supply to RF section. Hmm.

Eventually traced this to the inductor being open circuit. Must have damaged it via soldering.

Stuffed another one in. Same outcome. Fucks sake. Must need heat sinking.

Stuffed another one in with heatsink clips on the legs. Nope still dead.

Get DMM out and test it. Open circuit!

Get pack out and test a few unused ones. Open circuit!  Fucks sake.

Cracked one open with a pair of pliers and what did I find?

NO FUCKING WIRE in them.  :palm:

Well done China!

Oh, well, even at the bargain basement price it maintained up until the last minute it was ill-advised and someone else has picked themselves up a Bobby Dazzler Dactron1061 LOL (A.k.a: Datron 1061A with all the options).  :D

Ah, not mine. That just leaves me and BD139 giving each other the side-eye.
