Each came in a little plastic clamshell box. That was nice. Surprised that 3 of 3 as working (so far) after reading reviews of these sorts of displays from other sellers. Hopefully it stays that way!

I previously was using a different version of these display modules but the extra Z height from the soldered header on the PCB cutout was annoying for integration. I bought this set instead since it cleanly routes the connection to the back of the display, and also comes with the bonus of having threaded posts already applied for mounting. I've confirmed the display works with both the Adafruit GFX and LovyanGFX libraries using an ESP8266 dev board.There are a few things that would improve these modules. First, I think it would be nice for the provided cables to use male dupont connections instead of female, so they can be connected to a breadboard. For integration, I'm going to crimp on my own connector anyways, so it would be nice if the out-of-the-box connection was more useful during the prototyping stage.Second, the mounting posts do not have end stops. If you use a screw that is too long, you can accidentally screw through the PCB and push out the display and damage it. I accidentally did this but caught it and stopped myself before destroying the display. Ideally the threaded posts should be closed at the end.One smaller nitpick, the provided documentation (linked under "Product description" in case you initially missed it like I did) does not show the distance between the threaded posts. There is enough information to calculate it from what's given and you can verify with a caliper, but it would be nice to have that information provided as that is the most important measurement for mounting this display centrally on some object. English documentation would also be a plus but not a huge deal.If you are having troubles, make sure your connections between the display and your microcontroller are not too long, that you are correctly toggling Chip Select, and that your SPI interface is configured correctly with your library. In particular I tried inserting wire extensions into the provided cable to connect it to a breadboard, but this caused the connection length to be too long (or maybe the contact was flakey and it would have worked fine with a proper wire) and the display wouldn't process commands until I connected it directly to the microcontroller without any extensions.

It’s unclear if the product is faulty as it does not appear to work. I have adjusted the wiring to match similar products using the GC9A01 chip. All three modules have a slightly different behaviour.

Ok bad up front you’ll face head winds with community support. Frustrating as that maybe, the tech support from supplier was nothing short of exemplary. Elated to be wrong about my first review. However once it works this thing is going to set your next project to a different level of amazing.
