Figured I would chime in on my experience on ordering some of these.

I ordered 3 lots (qty 30) from the following seller: https://www.aliexpress.com/item/10PCS-FM1608-120-PG-FM1608-120-P-DIP/32413906510.html?spm=2114.13010608.0.0.OgK37h

I got out my shiny new Neoloch Inquisitor with the SRAM blade and got to testing. 75% were good right out of the gate. 25% were good on the 2nd test. Out of 30 pieces, one bad IC. Not worth filing a dispute over. I did find that once the Neoloch tested a unit bad, it would continue to test the same unit and subsequent units as bad unless the tester was power cycled. I don't know why that is, so I got into the habit of power cycling the tester after each test.

I paid $3.36 each for them including shipping which was a little high, but that was because they shipped via EMS instead of the normal China Packet thing. Unfortunately that was the cheapest shipping option. If you take out the one bad unit, cost was basically a hair over $3.47 each. It would have been nice if there had been a cheaper shipping option as the one offered ends up costing $1 per unit if you order in qty of 30. It's more per unit for a smaller qty.

Overall I am satisfied. I see the seller currently has them at 5% off so the order would be even cheaper today. I am halfway tempted to order another lot, but I don't need them so I probably won't.
