reliable RAM from AliExpress?

[Clipper]

Well, I'm considering upgrading the RAM, I have two Kingston Fury modules of 4 GB DDR3 and looking at the prices of the same model, the joke comes out at €70 (I want to put 16 GB)
But I've seen these RAMs on AliExpress that cost half or the same (two 4 modules for 32 and two 8 for 64 €)
The doubt is, are they reliable or are they a pain?

On Aliexpress, the first thing to do is to look at the seller's seniority, because there are many pirates who put things at a good price and then disappear. Recently, there were a few selling graphics cards that were supposedly retired from mining, which in reality was just a scam, and the shipments never happened.

And then, don't count on the slightest quality control in finished products if the price is interesting.

It can work out well. It can. You risk sticking something not too secure inside your beloved equipment with undetermined consequences. Also.

I wouldn't do it.

Salu2!
