My favorite Arduino nano clone board in spite of it's significant shortcomings.
In spite of it's shortcomings in terms of documentation, quite possibly my favorite nano clone. Great price, and it's a solid, well assembled unit.
Firstly, it's mostly just the form factor that I love: Easy to bread board, small enough to put into most any project, and wire wrap for permanent use (or desolder the headers). Uno power in a much smaller form factor, and USB programming.
My first gripe was that they used to ship in non-ESD safe packaging. My As of Jul 25, 2015, most recent order shipped in ESD safe packaging, BIG IMPROVEMENT. Well done Elisona. You get a star back for that.
My second gripe is clearly with the seller: The seller does not document in the product description that it doesn't use the FTDI chip and instead uses a WCH340G usb chip. Nor does the seller provide source URL for the WCH340G driver set in the product description or with the product/packaging. Also since the product is being sold multi-nationally, and specifically to the US, the seller should go through the trouble of arranging for a US language site for the drivers and English language data sheet on the WCH340G USB serial chip IMHO.
This should be documented in the product description; this is a CRITICAL MATERIAL DIFFERENCE between it and a genuine Arduino Nano and what they describe. And may make the unit unusable/unsuitable for certain applications that one would otherwise assume it is given the product description.
Beware: The WCH340G does occasionally freak out USB if direct connected as it draws more power than it should before identifying itself, occasionally causing a panic on the host system (in my case MacIntosh). Also if you intend to flash the USB to emulate another device (say a MIDI device, or as a USB host), you need to consider that you aren't using the FTDI chip, and that this may not be suitable or usable for your application. Use with a independently powered, optically isolated, USB hub for zero problems.
I use this only with a optically isolated, independently powered, USB hub when downloading, a hub that can send a full amp down stream without issue.
Last note: All the LED's on the board are RED, and very close together. I would prefer if power, were green, and the pin 13 led were another green or yellow or something other than the same color as the RX/TX lights and power light given their proximity.
I really don't like it when vendors sell goods on amazon, and customers have to rely on other customers (and customers have to do the work of the vendor,) for basic information and support that should be provided by the vendor. I don't know if contributing knowledge continues this more than the criticism & lowered ratings (assuming the vendor bothers to read the reviews of their product,) helps correct it.
I have several of these, and will likely have more in the future.
Drivers: directly from the chip manufacturer (Chinese Language site):
WCH 340 product home page: http://www.wch.cn/product/CH340.html
http://www.wch.cn/download/CH341SER_LINUX_ZIP.html (linux should operate fine without the driver)

Works well and programmed up easy once I re-soldered a couple pins.

Even More than a Uno, but much smaller and ready for prototyping!
This is an amazing little board! It essentially includes the entire Arduino Uno plus extra I/O pins (because the surface-mount package has more pins on it than the DIP package used in the Uno). This unit is designed to plug into a development or prototype board, and can also be directly soldered to a PCB or plugged into a set of strips acting like a socket. It comes with a very short USB programming cable.
At the amazing price this goes for, it is a steal, and an amazing little piece of technology!

These Arduino Nano are the best. It works error free
These Arduino Nano are the best. It works error free. I am using one of them to build a Logging Switch - can't be found out there. This supper inteligent switch gets it brain from the Nano. The switch controls an Electrical Heating System that I used to replace my Church Boiler. I substitued Marine batteries + a Generator + a windmill and got off the Grid. Somewhat pricey but no Heating bills any more!!!! in the winter. The actual Heating System Brain (an Arduino Mega) is switched between the batteries and generator. The switching with all activities logged is done by the Arduino Anano!! It's GREAT for this application - 5 STARS!

Works well with Ubuntu
Works great on my Ubuntu Linux system using USB port /dev/ttyUSB0 (or /dev/ttyUSB1, etc). Not necessary to install any new driver with this OS. Works well with Arduino Create. Well constructed. Shipped in a little anti-static envelope with the pins protected by insertion into a small block of polystyrene (?) foam. The USB cable is "exactly" one-foot in length, including the lengths of the connectors. This is a short cable - just be aware of the length.

Great buy with some caveats
Nice small Arduino that's easy to use with a breadboard and small/cheap enough for permanent projects and even comes with a nice little USB cable. Biggest handicap is that it doesn't come with (a link to) the required drivers. After some searching I found a set, but these would crash my Mac with macOS X Sierra everytime I'd plug in the board. Removal of these drives required some digging and wasn't at all straightforward. However, I found working drivers at [...] and now all is fine. I got two of these, and one had the LED for pin 13 not working (the output itself was fine), while the other one did. No big deal though. So, no 5 starts, but still a great deal given the price.

good low cost board
a low cost knock off Arduino it works well and unlike some boards like this has USB so you dont need to mess with an adapter. Came with the pins installed so keep that in mind if you do not want pins

Solid and nicely designed.
Sweet little breadboard-able board. Great little Nano clone - no problems getting to work immediately. Worked great for LED lights. I even powered a 50 LED strip (testing phase only) from the 5V rail and it worked fine.

Excellent product and does not have the DREADFUL FTDI chips.
Excellent product and does not have the DREADFUL FTDI chips. Avoid any product with FTDI chips as any windows machine will brick them (yes, I know that original chips are not affected but as a final consumer there is no way to tell until they are bricked, and FTDI is disreputable company that bricks other people's property---so I AVOID ANYTHING WITH FTDI in it, maybe it is fake, maybe it is not... you are a software update away from getting bricked.

Great Nano. Comes with boot loader already burned
Great Nano. Comes with boot loader already burned. Use your Arduino software and you are good to go.
Good static proof packaging. High quality.
On time deliver. Who could ask for anything more?
Thanks Makers and AlumiGogo.
