I'd go with a more reputable vendor unless you're on a really tight budget because Aliexpress isn't even that cheap, all things considered. There are fake chips and really low quality parts out there that will waste your time.
You can get a range of ESP32 boards from Digikey for $5-$8 and you'd have to scrape the bottom of the barrel to get them much cheaper than that on Aliexpress.
