Value for the money
Works as expected.

Great value, works well
The media could not be loaded. I got a pack of five for just eight dollars, which is a great price. These things can get really bright, so I use them at the minimum brightness.As others have mentioned, there is one flaw: the headers are soldered at an odd 45 degree angle on the face side, so they will most likely require re-soldering if you want to panel mount them.

Great Option
Displays all worked perfect, my only complaint is the pins are soldered at an angle which can make using the displays a little awkward.

Works great with Raspberry Pi Zero boards and Python
Works like a charm with my Raspberry Pi Zero V1.3 and Pi Zero W 2 boards. All I needed to do was download tm1637.py from Github (I'm using the depklyon version of tm1637, search for it), hook the power (VCC and GND) pins to 3v3 and ground pins (17 and 20 in my case) and the CLK and DIO pins to GPIO pins (GPIO23 (pin 16) and GPIO24 (pin 18)).For the python code add these lines in the appropriate places:import tm1637#declare variablesCLK = 23DIO = 24tm = tm1637.TM1637(clk=CLK, dio=DIO)#adjust brightnesstm.brightness(0)#then call tm.show(x) to print a string to the 7 segment displaytm.show(str(x))Then let the learning and fun begin!

Easier working with a module than individual digits
Not much to say but they are round-of-the-mill TM1637 4-digit 7-segment display. They use their own protocol so don't mistake them for I2C and there's actually you can do with them then you might realize in terms of animations thanks to the IC behind the segments.

Works as expected. Double-check your size requirements
I was not clear on what the measurements meant in the product description. These were smaller than what I ultimately needed, but they work well and are easy to use. The 0.36" measurement is the actual height of each digit on the display.I used these with an Arduino and an open-source library with no issue.

Good Quality
Work Great.. easy to program using a esp32

poorly assembled
The header pins were not soldered flush with the PCB on all five of the displays
