This product is designed for Australia, New Zealand, and China. It plugs in upside-down, so the Raspberry Pi logo is upside-down and the USB-C cable exits from the top. Also, there is a thin circle of plastic moulded around the edge which prevents you plugging it in to a socket or power board if there is something in the adjacent socket.

Very disappointed that a product designed these days should be so deficient. This product is designed for Australia, New Zealand, and China.

Yes got this 8gb model for a project. The 8Gb works better for what I had in mind, does not go into swap space. Used the 64bit Raspberry Pi OS on this one. Setup headless operation with Apache web server, Samba file sharing and Logitech Media Server. Attached a 1/2 terabyte of storage via USB, I can upload files from anywhere in the house, stream video to cast-able devices, stream music to hardware and software devices and the kicker is these files are in one would call a NAS so I have a few must have work files that I can access when I am away from my main PC... This setup I prototyped on a 2Gb one then tested on a 4Gb one

PS cooling is always an issue with the model Pi 4b so always have a heat management stratagary in place be it fans heat sinks or both

Having used the previous 3b+ model as a cheap and cheerful Raspbian desktop, the 4 makes a great leap forward into usability. Of course the biggest change is in the memory. With this 4Gb model, I've noticed a much better experience. Granted I'm not stressing it with a huge amount of local apps. But now you can have many more tabs open. Switching tabs and apps is "way" better. (Yes, that's a totally acceptable objective measure.) System paging is obviously much lower, and there's no sign of thrashing that used to occur from time to time with the 3b in use. BTW you'll still going to be happy running Libreoffice, VLC, ...

I've not done an exhaustive test or anything like that. this is just subjective feeling after switching boards. You do need to upgrade Raspbian to Buster for the 4. I find the Google apps I use daily work fine. Even the browser based Sketchup tool seems to be usable. In this later case i suspect the better processor and GPU help.
I'm only on a single head, HD tv through a standard HDMI cable. And using a 2.5A (13W) DC adaptor. The later is crucial to success. Don't try using these late model Pi's with any old micro USB lying around. It just won't work. I have just used my old micro to C adaptor (from my old Nexus) and have had no problem so far with the power. Similarly you'll need a standard to micro HDMI adaptor to use one of your HDMI cables lying around. Note if you're planning on going two head or 4k, then you'll need a new cable with the slimline plug. You won't get two HDMI adaptors side by side.
Can't talk to the heat problem you'll read about on the 'Net. It's bound to be hotter. Mine just sits out in the open collecting dust so plenty of natural airflow. No thoughts on increase in performance with the separate USB 2/3 buses now. Or the Ethernet moving from the USB bus. It has to be better though.
If you're looking for a simple, small, low power draw, quiet computing device with responsive desktop performance, IMHO you can't beat this for the price. The Raspberry Pi4 with 4GB does as advertised on the box

I have owned a Model 3 for years, continuously sending aircraft data to FlightRadar. This Pi 4 works as it should but don't buy this 1GB model unless it is for a low memory dedicated job. A 2GB RAM version would be the minimum. With this one, if you open Firefox and then Gmail it jams and will not read or send mail. Yiou then must unplug power to force reboot. I don't like the USB-C power plug nor the micro-HDMI connectors of which there are two. They are all flimsy and will always have adapters plugged in. The Model 3 had a proper power plug and full sized HDMI. I have owned a Model 3 for years, continuously sending aircraft data to FlightRadar.

I thought it would be months before I'd find the 4GB version available in New Zealand again, but PB came through in a couple of days. This is my third Pi 4, having used a 2GB and a second 4GB for two years now -- they continue to work well.

I'm using this one as a Docker container server on top of 64 bit Raspberry Pi OS. Running the containers is fine, but building images can be a little slow. Nevertheless, works great for my use-case.

I've paired mine up with an Argon Neo aluminium case. In this case, passively cooled works fine for New Zealand temperatures. It would get a little roasty if used in Australian summers.

Works well with the Jetson Nano 2GB. I was having trouble finding something that could maintain 5V under load. This is the one that finally worked. Works well with the Jetson Nano 2GB. I was having trouble finding something that could maintain 5V under load. This is the one that finally worked.

I've had some previous models, and this is a great evolution on those. I'm a big fan of the built-in wifi and bluetooth, which has made connectivity much easier. Most recent purchase is the centre of an aftermarket android-auto head unit for the car, which has no screen. I've had some previous models, and this is a great evolution on those.

The 4GB Ram version is probably overkill for most people, so consider getting the 2GB and spend the rest on some interesting accessories like the camera or a nice case.
The Pi 4 is all around a great little computer or base for an IoT project, with more than enough processing power for most Pi use cases (smart mirrors, 3D printers, Retro game consoles).
Fair warning that if you're using it to its full potential you'll probably need an industrial grade/app rated micro SD card or use a SSD as this thing eats through standard Micro SD cards.

Powers my 4B 4GB Pi up with no problems. Great value for money. Powers my 4B 4GB Pi up with no problems. Great value for money.

I picked this up to run Pi-hole on my network, was a little overkill for the application but the price was better than a lower spec model second hand! Its been running solidly for a few weeks now with no issues.

Pros - Great value new model
Cons - Nothing, buy one! I picked this up to run Pi-hole on my network, was a little overkill for the application but the price was better than a lower spec model second hand! Its been running solidly for a few weeks now with no issues.

Great wee item, previously had a P1, and this just absolutely blows it out of the water.
Running OMV with about 6 containers running, and it barely breaks a sweat!
Great service from PBTech as always, and super fast shipping! Great wee item, previously had a P1, and this just absolutely blows it out of the water.
