Doesn't work for me on Firefox mobile. Neither "mobile" site or Desktop versions. Hitting "Next/Enter" on my keyboard does nothing, there is no Submit button that I can see, and refreshing the page just resets all fields to defaults.
I don't want an Intel with 4gb RAM and a 256GB spinning drive, and OS included? No dice, that's what I'm offered. Without being able to filter results, its just another craigslist/amazon/newegg front-end ... a less useful one.
EDIT:
Turns out there are zero fanless non-Intel, 16+GB RAM, 1024+GB SSD/eMMC offerings with USB-C to list. Strange no-one is packaging an OrangePi 5 Plus like so, but I haven't seen a fanless heat-sink sufficient to make that a good idea anyways.
I had tweaked some of the options, but without clearing either-or-both of those last two, especially "fan-less", all I was getting was the five sponsored "results" the top, which changed just enough to make it seem like that's all the results I could get.
