They've all gotten good reviews for their hardware.
I don't think it's crazy to expect that Amazon could build a really solid "Basics" phone at around $200 - $250, since their competitors all do so with reasonable margins to spare.
I bought my phone from aliexpress last year. Since then, Haipai Noble has had 3 major versions, and a dozen minor hardware updates.
Decide on price, and find reviews online of popular Chinese phones. Make sure the have the hardware features you want at the price you want. And then follow safe buying rules. Don't buy from low sales vendors, nor bad scored vendors.
