    This seller provided the fastest shipping of any product I've purchased on this platform. I am extremely happy with the speed and how the item was packed for shipping. The item operates as intended and lines up with how it was listed. It's in good, working condition and was competitively priced. Any dirt was surface level and came off easily with some cleaning solution. Overall, very happy with this experience and highly recommend this seller.

    So this board is really a challenge to flash. I had to power cycle dozens of times before I could get to change the bios to support my cpu. I contemplated returning it after growing tired of the reboots but eventually I got it flashed to a lower bios. If you're lucky to have it working, don't update the bios unless it specifically is for your cpu.

    Surprising amount of features for a mATX board. 2 m.2 slots, 1 PCIe wi-fi card slot, and PCIe Gen 4 support are all very nice things to have.
