Review: Disappointing Performance and Misleading Product Description - I had high expectations for this mini PC, but unfortunately it has been a very disappointing experience. From the beginning, the computer was extremely slow. Simple tasks such as opening web pages, browsing the internet, and launching applications took far longer than expected. For a Ryzen 5 processor with 16GB RAM and an NVMe SSD, the performance was nowhere near what was advertised. After contacting GMKtec support and spending considerable time running diagnostics, checking BIOS settings, monitoring system performance, and exchanging multiple emails, GMKtec admitted that the desertcart product listing contained incorrect specifications. The listing advertised support for DDR4-3200 memory, but they confirmed that the hardware only supports a maximum memory speed of 2400MHz and said they were correcting the listing. Despite acknowledging the inaccurate advertisement, the only compensation initially offered was £8, and I was asked to reinstall Windows and spend several more hours troubleshooting the device myself. I did not consider that to be an appropriate resolution after already investing significant time trying to diagnose the problem. Thankfully, desertcart Customer Service reviewed the case and resolved it by approving a full refund. I cannot recommend this product based on my experience. If you’re looking for a reliable mini PC, I’d advise carefully considering other options. While the manufacturer responded to my emails, the product did not meet my expectations, and the inaccurate specifications significantly affected my confidence in the brand.
Review: Don't waste your time. - Looks pretty and compact, but functionality wise it is useless. super slow loading everything, won't even load settings menus properly or at all in some cases. Tried everything I could think of to speed it up, but to no avail. I would steer clear of this one.

### ⭐ Poor Product
*by J***S on 3 February 2026*

Not one for saying bad things, but the purchase of this product was a complete negative. All looked good on opening box, set up as per instructions, fired up, started its startup proceture, then a blank screen, power failure from "power pack" tested and started again, same thing, power failure at power pack!!!!!! Considering the price paid, this should not be happening. Item returned for credit, purchased a GEEKOM instead.
