  • Fantasic little PC for a few days and then.. and then
Like most reviewers before me, I have nothing but praise for this powerful little marvel. No tricks. No surprises. Very fast. Extremely easy to set up. The most surprising thing I can say is the packing. Reminds me of Apple and a few other high end European products. I bought it to replace an 4-5 year old HP mini because no matter what I tried, I could not get my ISP's bandwidth. Even had their tech here with me proving the HP was the issue. When I got this unit, I put side by side and simply moved cables, turned it on and voila, worked perfectly. Started adding my software little by little, testing the velocity to Spectrum. At one point, I stopped listing each change I made because it looked like there would be no issue. Unfortunately after several more additions, internet velocity dropped in half, similar to my old HP. There was no documentation. No W11 disk or USB. But when I googled W11, it said you can reinstall from the OS itself. So I pushed a few keys, went for lunch and when I came back, I had a fresh install. I took a speed check. Was getting 700+ mb on my wireless, so I started installing software again. This time I documented each step and did not stop. This time all my software was installed and I was still getting 700+. I used it for that day and proved I was able to work which involves a lot of video downloading, editing and uploading. The machine is a little powerhouse. The CPU is superb. Worked that day and the next. Halfway through the next day, I had to attach an SSD through a USB port to get at some of my files. I'd been using this SSD for about a month in my other HP mini. Avast runs nightly. AFAIK it was fine. Shortly after I plugged it into the CK10, the screen went black. I rebooted the CK10, it came up doing crazy things. Several reboots and several combinations of weird behaviour like the USB mouse wouldnt work. The next reboot, the USB keyboard wouldn't respond. Next reboot both failed. Next reboot both worked. I logged into W11 and everything worked for 20-30 secs and screen went dark. I rebooted again. This time the bios didn't appear. Reboots after that had to be pulling the power to get the bios to appear. I removed the SSD, same behaviour. After several more reboots, I gave up. Packed up the unit and went to Amazon returns to replace it with another. But Amazon didn't offer a replacement. I assume because it was bought on Amazon Prime day, I couldn't swap it. If I wanted a replacement I have to pay $100 more. Needless to say, I'm not happy. It was a great machine for 2-3 days. I have never seen anything like this before. Since my SSD still is completely clean with both Avast and McAfee, I have to assume there was some kind of hardware failure that was either a matter of time or caused by plugging into that USB port. I will re-order something. I will look at CK10 Chinese competitors now that I'm paying full price. To anyone reading this review, I'd recommend when you get the unit, put it to work asap and work it for the 30 day return period. I will certainly make sure I do that for the next one. EDIT 7-27-2023 Customer service contacted me within a day of posting 3 stars. Asked what they could do to make it right. Engaged in several messages until I figured it was either a bot or someone English comprehension challenged. After I thanked them very much but no thankyou, I received a message from another return address that flat out offered to replace the PC for me to try it to see if this would satisfy me. I agreed. One is on the way. I'm 99.5% sure this PC will be fine. I'll know for sure next week. Have to give customer service 5 stars. Cant say I've ever seen a vendor give you an expensive product to try for 30 days no strings, no credit card attached. These people really do adhere to 'the customer is always right'. Update Apr 21/24 Forgot to update after I got the replacement. It worked perfectly. 7 months later, still working almost perfectly. There's an issue with BT headphones. I have 3 different sets. None of them connect as expected. I dont remember who told me but the but the solution was go to Device Manager. remove the included BT driver. Plug in BT USB adaptor. Turn on your headphones. Work fine. I never turn off my PC but when I occasionally take it to a client site, I have to repeat the process. Done this easily 15-20x. Works every time. Maybe by now, if you buy the PC, someone at Kamrui has fixed the bug. I could likely call for a fix but I'm happy with my quirky little process. Buying another one today for backup. Update 6/21/2024 Been using it out of the country on 220V since 11/23. It's on 24/7. Business & Personal. Lots of big spreadsheets and video. Performance same as it was when I got it. Feel it several times a day for heating (old habits die hard). Always cool to the touch. M.2 always runs in the mid 40's (centigrade). On June 17, M.2 health dropped 3% due to bad sectors discovered. Automatically used us 9% of reserved space to handle it. As of today, HDSentinel reports M.2 at 91% health--still excellent. I will replace it with another 512M.2 when I get back. Bluetooth still doesn't work because I didn't call/email tech support when I first noticed it. I bought a Bluetooth adapter which works when I disable the onboard generic bluetooth service every time I use it. When I get back home, I'll ask tech support for an update. I ordered another Kamrui as a backup. Should be sitting on my desk when I get back. Someone said these miniature computers are the future of PC's. I've been carting it around in my backpack for months now, from place to place here in S.A. I remember the days when we carted around mini towers from place to place. Definitely a better solution. Easier on the back too :). Also less likely to be stolen. Local robbers here dont know it's a computer. Threw it on the floor and stole the monitor instead. Nice. ... show more

  • Surprisingly Powerful Mini PC – Worth Every Penny!
Size: AMD R7 5825U 16GB+512GB
I wasn’t expecting such a powerhouse in such a tiny form factor. This one has blown me away with its performance, versatility, and value. It's my go-to machine now for both work and play. Pros : 8 cores make multitasking effortless Triple 4K display support is perfect for my home setup WiFi 6 & Bluetooth 5.2 is the lightning-fast connectivity. Super compact and easy to mount behind a monitor. Super easy installation Cons : Don’t expect high-end gaming, but light titles like CS:GO and Stardew Valley run smooth at 1080p. Great for emulators and indie games. 4K streaming is flawless on Netflix and YouTube. Overall : This mini PC punches way above its price. Quiet, fast, and shockingly capable—it’s the perfect pick for anyone needing a small but mighty desktop. ... show more

  • Great little pc with one issue
Size: AMD R7 5825U 16GB+512GB
This little mini is quite capable and quiet. If you get it on sale it is a great little pc for media and light gaming. The only downside really is the included ssd. They should have included a faster m.2 drive instead. They could have done so for maybe a cost of 5-10 dollars more at most. So when I got this I wasn't quite happy with the ssd performance. I got a new m.2 and put a fresh install of windows 11(always do a fresh, clean install with a new pc) on it: I got the Crucial P3 Plus 1TB PCIe Gen4 3D NAND NVMe M.2 SSD. (Don't worry, the Windows 11 license is unaffected by the drive change and fresh install.) Now don't get me wrong, if you're using this just as a media device the included ssd is fine. Or if you are upgrading from a really old machine that uses a mechanical drive, you'll be delighted with the included ssd drive. However, M.2 drives are just a lot faster, and now this thing boots in no time and is now really nice and snappy overall. You can definitely tell the difference. And then if you want to you can reformat the original ssd and use it for a little extra storage. I have a large external drive, so I elected to not use the orignal ssd, and keep that slot open for slightly better internal air flow. This also came with 1 stick of 16GB DDR4 RAM. If you have 2 sticks of 8GB laying around, or 2 sticks of 16 GB, that would be even better. If not, the single stick is OK. But if you want to do a little gaming, 2 sticks is a must in my opinion. Just better performance. But serious gamers obviously should build their own pc. For someone like me, though it is perfect. I can have as many tabs open in my browser as I like, watch a video, and even game a bit with older titles and lower settings. I've even played less demanding games and watched videos at the same time. It's only a couple months old, but no issues so far. ... show more

  • Great, with a few caveats
Size: AMD R7 5700U 32GB+1TB
This far, the PC has been rock solid. Fast and silent. First warning, this takes some work to get into: 1- pop off the 4 rubber feet. 2- unscrew the now revealed screws. 3- unscrew 4 more screws holding on the interior cover plate. As I am firmly in the "screw Microsoft" camp these days and planned to use Linux, I had to source another Wifi card as the unit this comes with has NO drivers for that OS. Once bolted back together, installation was fast and straightforward. Every app I've thrown at it runs cleanly and very quick. Handles 2 large monitors perfectly. I'm very happy with the purchase. ... show more
