I'm looking to upgrade the DDR4 SODIMM memory in my ThinkPad, and I've found listings on AliExpress that are much cheaper than comparable options on Amazon. Has anyone had good or bad experiences buying laptop RAM there? I'm especially wondering whether the low prices usually mean defective, refurbished, or counterfeit modules, and whether the savings are worth the risk.

It can work, but treat unusually cheap listings as a warning sign. Check the seller’s history, reviews, sales volume, and photos from previous buyers. If the same module is dramatically cheaper than every comparable listing, it may be defective, refurbished, or falsely labeled.
There are occasional bargains, but reputable sellers usually aren’t selling good RAM at unbelievably low prices. Faulty or recycled memory is more common in the cheapest listings, and returning it or getting your money back can be a hassle.
Look closely at the ratings and buyer feedback, but remember that a high rating alone doesn’t guarantee the RAM is genuine or reliable. Try to find reviews that mention the exact capacity, speed, and compatibility.
For a ThinkPad upgrade, I’d usually buy from a reliable local or established hardware seller unless the AliExpress seller has an excellent track record and the savings are substantial. Also account for possible import charges and the time involved if something goes wrong.
