FIXPHONE, which I linked to above, is the official China PhoneFix storefront on AliExpress. As I've said, they're good. They also have a
standalone website you can order direct from, but Ali is usually cheaper, especially with shipping to the US. For example the ST-862D from their Ali store is $192 shipped for the kit including bent nozzles (which I linked above). On their website the same kit is $135.99 + $65.99 shipping, so $202 total shipped.
My only experience with Aliexpress has been to order a switch on Feb 4 and it still hasn't shipped. I don't know how many eons it will take to get here.
It's not as common these days as it used to be, but it's not unheard of to take a week or two to ship out of China. It's also pretty common that things move but tracking doesn't update. I've had things show up at my door that tracking said was still in China. But that's much less common than it used to be -- I have been ordering a few times per month and things typically ship within a day or two, although they can get hung up on the way to the port, in customs, and in country.
Just to highlight that it's not always a China problem: I had ordered a DMM from Ali in January. It arrived in my state in about 10 days. It then spent the next 14 days bouncing around
inside my state going back and forth between the same post office distribution centers and a small town post office on the opposite side of the state from where I live. I called that post office and as soon as I said my name and described the package, she knew what I was talking about. She said they had been trying to figure out why it kept coming back to them, because the name, address, barcode, and everything about the label was correct. Yet it kept routing to them instead of my PO. They had to deface the label before sending it back to distribution so that the automation would kick it out and force them to manually route it. I finally did get it several days after that.
