Good POE experience
After testing a few hats found this to be the absolute best for running pi 5s off POE. Slowly converting my current set up from Pimoroni NVME bases to this configuration for my 10” rack. Works without issue when I have four plugged into a TPlink tp-sg105mpe; but will be moving to a ubiquity flex 2.5 soon to cut clutter (I need 8 ports to run all the pi’s when complete). I wish there was an option to get them without the POE hat because I already had them for all my current nodes, but all in all it’s priced well. They also give you two connector ribbons in case you screw one up, which is nice.

Works as advertised, Configure your firmware!
If you need to connect an SSD to your Pi, this definitely works. Make sure you follow the instructions to configure your Pi's firmware though, otherwise you won't get proper speeds. It meets the advertised speeds, isn't terribly difficult to install if you know how to handle electronics, and feels good quality. I haven't had any issues, so I'd say this is worth it.

Great PI Hat!
Great POE Hat for the Pi 5. Has worked solid and the FAN helps keep the Processor Cool. Slot for extra storage is great to as do not trust a SD Card that much for production use of data storage with a PI as read and write cycles can be much lower.

Works great, but not compatible with many enclosures
This board works really well. The thing that is mildly disappointing is that the board extends over the top of the ports. If you look at all the official HATs from Raspberry Pi, none of theirs do this. This creates a little bit of a physical compatibility issue with a lot of rack mounts and other types of enclosures where there are slots cut out for the ports. This board protruding too far forward can prevent things from physically lining up. If the rack/enclosure has holes that the Pi should line up with and be mounted to, this board jutting out too far in the front can throw everything off by a few millimeters so that the Pi doesn't line up with the mounting hole. I had a very expensive rack that I needed to drill my own holes in to make things fit and it came out ok, but there's still a bit of an issue in that the Pis are all recessed a few millimeters now instead of their ports being flush with the front face. Kind of annoying and all on account of the board jutting out too far in the front. Other than this, these boards have been great. Tech-wise, no issues.

Just what I wanted, combining PCI-E and POE for the Pi 5
This combines a 2280 M.2 and POE for the Pi 5. What would make it perfect would be a full 5A of output as opposed to 4.5A. It will show the lightning bolt as it's not 5A for awareness, and likely limit downstream current. But, I had no issues running the NVME HAT along with POE, and it worked just fine with a USB hub for my 2 port keyboard (lighted) and mouse, and HDMI so the current was sufficient. The listing was accurate, though. It would also be nice if were not as tall, much like the official Pi 4 POE adapter with the planar component and solid capacitors. This came with 2 M.2 screws as well as another anchor for smaller drives. The 2280 hole is fixed. It seemed to support PCI-E 3.0 just fine as the drive speed was around 900MB/s. There is a version for up to 2245 that is shorter, but it lacks the 2280 compatability and the pins for 3.3, 5, and 12V. I also like that the GPIO extenders were long enough to still use the GPIO; the official HAT is not. Maybe one day the official adapter will come out and still be compatbile with HATs and the official cooler, though I doubt it will work with all of them and also put out 5A given how small it will be.

Sweet little doodad
Works perfectly. Happy customer here. I hit a snag setting up but once I checked things out I realized that the ribbon wasn't properly seated AND I didnt seat the ssd completely AND finally I didnt seat the PoE header all the way. After that hiccup everything was great. IF you have issues during setup/config check your connections.

Using for my All Sky Camera so I just have to run an outdoor Ethernet cable
So far, so good. I've got some issues with the software, but this board is running fine with my Pi 5 in an outdoor sealed electrical box at the end of 200 ft of outdoor Ethernet cable. I haven't monitored the daytime temperatures of the Pi inside the box in the sun, so all I can say is that it's still running after 2 weeks outside. I know the power converter and the Pi generate heat, so that will likely limit the system's longevity in my application. I considered mounting a waterproof 5V power converter outside the box for heat reasons, but that got too problematic when trying to use a standard POE+ power injector on the house side.

Best hat/shield for Pi 5
Best shield, my second one has some nice improvements too. Instead of one large cap, there are now a row of surface mount capacitors, probably for better power filtering. These are completely awesome for a Raspberry Pi 5. The cooler is official hardware and the hat is awesome. Fast NVME to boot and operate, check. POE to power the Pi, check. Stays cool and runs super fast thanks to the cooler, check. Anytime I buy a Pi 5, I'm buying one of these to go with it.

Funciona a la primera. Solo tienes que tener cuidado con el Flex del pci, habilitar pcie gen 3 si tú Nvme es 3.0 y listo.

Perfect fit and integration. This hat quickly expands the boot drive to a larger, faster, and more reliable NVMe SSD. The system boots much quicker than from an SD card. The PoE+ allows for reboots over LAN and greatly simplifies the cabling. I would happily buy this again for other units.

Funciona bien con un nvme verbatim 4 tb, aunque en la pi marca un msj de bajo voltaje
