I purchased one of these Kingdel mini pc's on AliExpress, but feel compelled to warn others how this company operates and will treat you if you purchase from them, here's a summary of my experience with them:-The Kingdel pc fried my fried hard drive, even though it stated on the product page that you could install 2.5 in hard drive, the computer PSU/Mobo clearly could not handle it.-If you need to send back their faulty/broken product, for refund or warranty, they will not pay for shipping, so expect to pay around $80+ USD (If you're in US or Europe) just to ship their broken pc back to them in Shenzhen, China.-Expect terrible customer service, immediately after starting the refund process, their customer service rep accused me of intentionally breaking the computer, demanded evidence (which I provided plenty of video evidence that the pc was broken). Yet they were still belligerent, rude, and difficult in every step of the refund process.-Kingdel is not a reputable company, when I tried sending the faulty item back, they demanded that I falsify the custom's document and declare the item's value at $150, when its true value was $500. This is custom's fraud, which is illegal in most countries, so I refused to do so and reported the item at it's true value. Kingdel got very upset by this because they didn't want to pay any custom's dues, and to try and screw me over they attempted to cancel my refund all together even though the item was clearly sent back to them. So in summary, they wanted to keep the pc and steal my money.TL:DR If you buy a Kindel pre-built mini pc, expect for it to fail (which will likely happen with these poorly made Kingdel products). And if you need to send it back for a refund/repairs, expect to receive the worst customer service of your life, and expect to pay up to a 100 dollars just to ship it back to them. Don't take that risk, don't buy from this company, stick with more reputable manufacturers (hp, asus, dell, etc.) that have good return policies/warranties and can process returns in your country, otherwise you risk getting ripped off in the same way I did.
