As I already said, the fanless computer is very nicely built. However, contrary to my previous impression, it is also electronically superb, and the Wi-Fi problem I encountered was mistakenly blamed on the computer.The team in Kingdel gave me fantastic service and explained why the Wi-Fi was not working (it was my fault). After their explanation, everything is working flawlessly.I am pleased with this product, which I use for field testing an R&D automatic agricultural spraying system project. This PC's fanless feature is necessary to avoid the entrance of droplets into the PC.I have already ordered another computer from the Kingdel line of products since it does what it is built for.
