The product itself is top quality. I had never done an electronic project before- even against the recommendations I started my first with the Null pi 2. And even as a beginner, I was able to solder and assemble the project with hardly any troubles. I spent a full Saturday about 8 hours assembling the kit and another day to print and assemble the 3D case. The OS works out of the box and it plays 2D games very smoothly. Most N64 games are just too much for the Pi Zero W.
The documentation was good most of the way through but I did have some difficulty so I hopped onto the recommended discord channel for more questions and assistance. Unfortunately the seller has no sense of public relations and kept his answers short to assembling the kit. Which would be fine but he became aggressive towards me asking further questions about customization and grew hostile over engaging with the community. It's a shame because I was so happy the product I had planned on being a part of that community and buying the next round of null kits indefinitely.
The whole ordeal was upsetting so I'll leave anyone with this advice: stick to questions about the build steps only. Luckily I did make some friends from the channel who were able to help finish the case assembly steps with (For those in the US: those 3m x 8mm screws are a little elusive! You may have to ship some to you from amazon) and I'm thankful for that.
I finally got around to assembling this today, I had to get through my backlog, and I was really looking forward to this kit. Unfortunately, it appears I have a dud unit. My Raspberry Pi0 is brand new, and I put on a stock image of RetroPi prior to starting this build and it works fine. I assembled according to the instructions, and a few videos that I found on youtube with no effort, and took probably 90 minutes. I had no problems with any overheating pads, or bridged joints. I've done plenty of SMD components prior to this. Plus having only one surface mount 3R9 resistor doesn't make it hard to assemble.
Metering around all the joints after putting the Pi0 in place seemed ok. I would like to mention that it would be beneficial to add pads to the bottom of this board so you can test the actual connectivity of the joints, instead of guessing that the solder has taken. The instructions would be better if they ditched the color coded schematic, and instead had a proper diagram, so you can test all soldered points, without confusing the slight variations in colors.
I believe my screen is faulty, it only shows a white background. Nothing flashes or flickers even slightly. I have reflashed the image twice, thinking it was the problem, then went over the joints and tested the Pi0 again with a RetroPi images SD card, which displays perfectly over HDMI. The little switch plastic nub has now broken off the power switch, since troubleshooting this device is less than ideal. The power down button at the bottom right initiates the shutdown command to my PI, and i can see when to turn it off as the LED extinguishes.
To date, in my 30+ years of soldering, this is the first device that has ever failed. Again, I believe it's the LCD, but since I don't have one spare it's pretty hard to confirm. Putting it back in the pile of "I'll get around to it" again. Assuming it's just these cheap LCD's from aliexpress?

I decided to buy this kit as I wanted to improve my soldering skills with a significant challenge. The kit provides all the necessary electonics, leaving space for the final user to choose a case (I went for a 3D printed one). The assembly process is straightforward and the instructions are really good. I recommend using a multimeter throughout the whole procedure.
