Review on Enhanced Cooling Fan and Heatsink Set for Raspberry Pi 4B, GPIO Expansion Board with LED for Raspberry Pi 4B/3B+/3B, DC5V 0.2A - MakerFocus by Robert Espinoza

Product works great and matches the ad. 2 small downsides on the board, 1. I had to desolder the fan to be able to move it and put it on the back of the board to fit the case height restrictions (the boards are a bit big for what they do), 2. I had to desolder the fan. Because they didn't solder the clip or pins, they soldered the fan wires directly to the board without allowing the service wire to sag, so it can't be replaced/repaired without damaging the board. The best recommendation for product developers. Remove the GPIO pins and turn the hat into a standoff to maintain the height (add some brass posts to adjust the height and secure) and replace the soldered fan wires with 2 rectangular pin headers. will make the product much more versatile, easier to maintain and usable in any system.
