Less than three years of use and the eMMC module failed. This means that I lost my Windows license, all my data, and installation configuration. The computer boots to a black shell> screen. I contacted MinisForum support and Melody said "some part failed". Wow, shocking information. Then said no warranty. I said I need a working computer, I accept used, refurbished, whatever. Melody was intransigent, no warranty or service options for you! Be warned that if you buy this product, it will only last slightly over two years. That's it! There was no apology from supplier regarding data loss.
