I’ve been using the Kamrui Mini PC for a few weeks now, and I’m absolutely thrilled with it! As someone who needs a reliable computer for both work and entertainment, this little device has been a game-changer. It’s incredibly fast—thanks to the powerful processor and SSD, I can switch between tasks like video editing, streaming, and browsing without any lag. The compact design is perfect for my small desk, and I love how it doesn’t take up much space but still delivers desktop-level performance. Plus, setting up my dual monitors was a breeze with the HDMI ports. What really stands out to me is how portable it is. I often work from different locations, and being able to just slip the Kamrui Mini PC into my bag is so convenient. The Wi-Fi 6 support ensures I always have a stable and fast internet connection, which is a huge plus for video calls and streaming. For the price, this mini PC offers incredible value—it’s powerful, versatile, and perfect for anyone who needs a compact yet high-performing computer. I couldn’t be happier with my purchase!

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.

My initial review of the KAMRUI E3B Mini PC was a 1-star rating due to a complete hardware failure after five months of use. The system suffered from frequent Blue Screens of Death (BSOD) and would black out and reboot entirely whenever I attempted to play videos or handle multimedia tasks. Following my review, the seller proactively reached out to resolve the issue. They provided excellent customer service and issued a full refund for the product without any hassle. While the specific unit I received had technical flaws, the seller has proven to be highly responsible and trustworthy. As previously stated, the KAMRUI E3B Mini PC failed after five months of use, experiencing constant BSOD crashes and reboots during basic YouTube video playback. The hardware itself was a disappointment for my productivity needs. Recommended if you would like to buy this one then you can at least rest assured that the company stands firmly behind their products and takes care of their customers. My rating to 4 stars purely to reflect their customer support . Not the PRODUCT. --------------------------------------- Previous Rating and Details ----------------------------- ⭐ One Star - Complete Failure After 5 Months of Use - Do Not Buy! Initial Review: 5 Stars (Mistake!) When I first purchased the KAMRUI E3B Mini PC with AMD Ryzen 7 5825U, I was incredibly impressed. It was fast, quiet, and seemed like a powerhouse in a tiny form factor. For the first few months, it performed flawlessly, and I happily gave it a 5-star rating, feeling confident in my purchase. Unfortunately, that initial excitement has completely evaporated. After only about five months of use, this Mini PC has become utterly unreliable and is actively hampering my work. The system now faces constant, severe stability issues that make it unusable: Frequent Blue Screens of Death (BSOD): The blue screen appears with alarming regularity, often without warning, forcing my work to halt and risking data loss. Video Playback Failure (Black Screen & Reboot): This is the most frustrating issue. I cannot watch videos for any extended period—not even simple YouTube videos. The screen will suddenly go black, and the entire system will immediately reboot. This happens consistently when under any kind of video or multimedia load. Unreliable for Work: The constant crashes and reboots have made this machine completely untrustworthy for daily tasks. I bought this to be a productive workstation, and instead, it has become a source of immense disappointment and stress. Conclusion: A Product That Will Not Last My initial positive experience has been overshadowed by these critical, deep-seated stability problems. The KAMRUI E3B Mini PC with the Ryzen 7 5825U has demonstrated a severe lack of long-term reliability. The consistent blue screens and the inability to handle basic video playback without crashing strongly suggest a fundamental flaw, possibly with the cooling, power delivery, or specific component quality. Save your money and your frustration. This product will not last, and its early failure is a major letdown. I have downgraded my rating from a temporary 5 stars to a definitive 1 Star. ---------------- Previous Rating 5 --------------------- 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.

Very disappointed and you GET WHAT YOY PAY FOR! I have been in the IT business for over 35 years, and I have always used Dell products. Then with customer concerns over rising priced I started deploying the mini-PC’s and what a disappointment with the lack of support and inferior hardware quality. Sure, out of the box the compact size and lower price seem appealing, yet this is “short-lived” and DON’T expect to get 6-8 years out of these like all the Dell products perform. The fans will fail first and try to get BIOS updates, forget it I have sent so many emails to Kamrui support and its NEVER resolved. I now have M.2 SSD failures and after the drive is replaced Windows-11 fails saying no TPM Support. Searched and searched and searched more and have now sent 3- support emails trying the get a W11 Supported BIOS and still days later NOTHING! Spend the extra money and buy Dell when there is REAL SUPPORT and an organized list when you will not have to spend days trying to get your hardware drivers. Spend the extra money now or regret it later with this inferior crap that will cost tons of hours or waited time! I just search my Amazon orders for Kamrui and I have placed 42 orders wit the first dating back to October 2021 and with those 42 orders I have ordered a total of 63 Kamrui systems for my clients and I have regrated starting last year when these systems started failing one after another. Consider yourself lucky if you get past the three-year mark, which is where I started seeing these failures and I should have reported it over a year ago. Now that its NOT just the fans but now the M.2 drives failing and BIOS that DO NOT support Windows-11 it’s become MORE than AGGERVATING!

Mini computers are wonderful!!! So small easy to move around and work very well. Well first off I don't like laptop computers. Keyboards are too small. I like a desktop computer and have always used that. Full size keyboard and mouse. Mini computers can do all the things I used to do on my desktop while taking up a small amount of space. I got the first one and it was amazing!!! Now I have the 2nd one up and running. Went with a higher end one around $250 see below. It is amazing, faster more access and higher optics for my monitor a full size tv. The ease of setup and the updated version of Windows 11 makes it so much easier. This was sold as a gaming computer which makes the monitor work so much more smoothly.

Update: Have had computer for 4 months now. Still very happy with computer and Kamrui product support! Still recommend. Great mini-computer. Although the only thing mini about this computer is the size! It boots up to Win 11 in less than 30 seconds. I had several older laptops, a Lenovo and HP. Both of which were not compatible with win 11, so Microsoft forced me to buy a new computer. I know I didn't really have to, but it was time to upgrade anyway. I was using the best of the 2 laptops as a desktop anyway. (Using external monitor, keyboards and mouse) So I went for this Kamrui Mini Computer. Very impressed after about 2 weeks so far. Everything worked right out of the box. I was having difficulty getting my cell phone to connect to Microsoft Phone Link. (Android app is called Link to Windows). I emailed their tech support and was very impressed with the customer service. All communication was through WhatsApp. They are in China so 12 hrs ahead of us. That was the only inconvenience. But they were able to help get all the settings set up and everything is great now. It has a total of 6 USB-A ports and 1 USB-C port (That will support a monitor), 1 HDMI port and 1 DP port, so can support up to three monitors. WiFi 6 and Bluetooth. It even looks great sitting on my desk! I thought about mounting under the desk, but it is so small I didnt need to! I would highly recommend!

If you are going to use it as is, it works fine. If you ever need to upgrade the m.2 drive, good luck. I tried 2 different ones, other than the one it came with, and no luck. Looked at their website for a hint and it's an absolute joke. It looks like they put the bare minimum together to MAKE it look legit. I ended up with returning and going with a BeeLink and had no problems putting my own m.2 drive in. Their website looks like legit and appear serious about what they do. The only reason 3 stars is because it works, but would not recommend making future upgrades. Company seems like a fly-by-night.
