I buy Lego from Ali. It's so much cheaper and the quality is same.

I bought an intel i7-5775c for like £70 about 2 and a half years ago from Aliexpress. Really strong cpu for the price, overclocks well and has meant that I haven’t had to upgrade my motherboard and ram to ddr4 yet.

My first (so far) purchase has been wireless adapters for my earphones (iems). Signing up was interesting as they do not allow ye to register with an email that has aliexpress in it.

So far said adapters are good, really good (trn bt30)

Some arts supplies are good. I'm very poor and I hate consumerism, but I can't really afford the good stuff so I sometimes resort to stuff like this. They do good acrylic markers and have a huge pack of normal markers that's also really decent.

I got a decent little fanless i5-based computer with 6 ethernet ports to use as a router, and it was cheap and works well running OPNsense. That's about the only thing I've bought on AliExpress.

I got a really good Glock 18 style electric water pistol off Aliexpress for this summer, at half the price they were being hawked for on Amazon. It even comes with a drum magazine- it was great for a music festival I went to recently!

I've bought from aliexpress in the past for obscure electronics that you can't really get anywhere else for a good price. But I will never shop at temu, I am incredibly suspicious about how they have such an incredibly large advertising budget yet their prices are so low. Either it's a straight up scam or they are expecting to make a lot of money later down the line
