4 years of perfect reliability!

Reviewed in the United States on April 4, 2024

If you ever wondered whether such devices last, then 4 years should prove it!
This Raspberry Pi 4 has been used as a desktop PC, has run retro game emulations extensively and now is in use running an Open Source synthesizer project. It continues to run flawlessly even after a very bumpy house move.

Boot times are mere seconds into the Raspberry O/S, but it can also be used headless, as with the synth software. Switch on, wait 10 seconds and it's ready to use.
Really, these sit somewhere between the most powerful Arduino type boards and a full desktop mini PC.
Immensely capable hardware and software for the price, from the biggest company in the game.

I would recommend fitting a heatsink (as shown) , so that all day use won't ever be a problem even in summer.

Perfect Product - But Waaaay Above MSRP

Due to supply chain issues, had to get this at a ridiculous price for a time-critical project.

Exceptionally Versatile and Affordable Mini Computer

Reviewed in the United States on March 1, 2024

Size: 4GBVerified Purchase

This was my first Raspberry Pi used for a robot kit. It won't be my last as there are a huge range of applications.

Know that this is a completely bare computer. No power supply. No interfaces (keyboard, etc.) of any sort. No permanent storage. To actually set up the device you need a power supply, a mini SD card to act as the "drive," a keyboard, mouse and monitor.

There are four standard USB connections (2xType3; 2xType2), two LAN connections and two MICRO HDMI connectors for monitors. There is a 30-pin bus affording power, switching and feedback for external devices. Wi-Fi and bluetooth are built in as is some sort of audio with a 3.5mm stereo jack provided.

Downloading and installing Raspberry OS was simple and the device boots and resets very rapidly. The included apps are largely open source and functional.

Bought it a year ago and left it connected all the time and still on with no issues. Will buy another one soon. Highly recommend it.

Yes, it's a pi 4

Official Raspberry Pi 4b. Just like I bought at another vendor. With these finally coming back down to regular price, I highly suggest picking one up for tinkering, experimenting, practical uses. I have 2 identical 4b's I use in redundancy for pihole and DNS servers. For laymen, that is for adblocking and privacy from ISPs. I have them both on different POE hats, works with both. Good buy at the normal price.

Quick and easy setup as expected. That was my first review however it's not Amazon's fault but be cautious this is the second one I've had brick itself within a couple of weeks and at these prices that can hurt especially us old folks on SSI

One Of The 10 Best Computers Ever

Reviewed in the United States on March 6, 2020

Size: 4GBVerified Purchase

I've been using computers in one capacity or another since the early 1980's, and I've never been shy with my criticism of any computing platform. I also try my best not to be religious; I'm typing this review on a MacBook Pro, but on a daily basis I also use Windows, Linux, Android and OpenBSD. That said, I really do believe that the Raspberry Pi is one of the 10 best computers ever ... and that puts it in high ranks with the likes of the original Macintosh, the original IBM PC, the Commodore 64, and the original iMac.

Sometimes the best computers are the best because they're cheap and approachable, and that's exactly what the Raspberry Pi strives to be. It will never win in any benchmark tests, nor will it become the platform of choice for compute intensive operations like bitcoin mining. But it more than makes up for that by being the sort of board that an auspicious 10 year old could learn and master, and then go on to build any number of gadgets and trinkets. This is the Lego of computers, and its two digit price point means that the cost of making a mistake is much lower.

Cheap isn't enough, though. By running Linux (and a reasonably well developed distribution of Linux at that), it gives people a platform on which to learn virtually every programming language that can be practicably used in 2020. The Pi can be a LAMP server for PHP web development just as easily as it can be a platform for Python, C++, Java, or dozens (perhaps hundreds?) of other languages that could be useful.

And it's not just languages. This could be a platform on which to learn any number of frameworks, from Hadoop to Spring. Or it could be used to learn networking. Or even hardware development, with its robust busses and interfaces.

Or maybe learning isn't your thing, in which case the Pi could be a file server. Or a media server. Or a web server. Or an email server. Or a robust little desktop for all manner of noodling. For those that tinker with 3d printers, the Raspberry Pi opens up a world of true computing power (in a tiny package) to all manner of 3d printed gadgets.

And here's the best part: when someone "outgrows" the Pi, there are a plethora of platforms on which to migrate. In fact, one could even argue that "if you can make it work on a Pi, you can make it work anywhere."

Criticisms abound about the Pi, and that's always going to be the case with any platform. Nothing can be everything to everyone, especially at a price point like this. Some of these criticisms are fair (like the Pi's incompatibility with the current Apple USB-C power bricks), and others are simply people looking to be armchair critics (like the criticism that there's not enough software). And as is the case with any computer purchase, you'll increase your chances of satisfaction if you have a good objective sense of what you're looking for. But if you don't, this is a very low cost way to get into the world of nuts-and-bolts computer tinkering, and for that reason it more than deserves five stars in my books.
