A part of the review has been auto-translated.
Windows 11 Pro installed on M.2 2280 SSD SATA 512GB . I replaced it with NVMe and reinstalled Windows 11 Pro, but I did not have any problems with activation. However, there is no audio output or Thunder Bolt 4 driver. I can't find it when I search it and my MU05 can't output audio. In addition, the shape of the power plug is Chinese specification and comes with a conversion plug. The power cable (Mickey-shaped 3-pin) after the AC adapter can be replaced with BUFFALO BSACC0820BKA to make it a Japanese specification. The problem is that the description of the web page at the time of purchase was false. In addition to the M.2 2280 SSD, there was an indication that a 2.5-inch SATA SSD could be added up to 2GB. When I actually opened the MU05, it was impossible to add it. I asked Banggood and confirmed that I only fixed the false statements on the web page. Although I bought it because I was aware of the risks of Chinese PCs, the study fee was higher. We can't deny the risks of backdoors and we don't recommend buying them.
