Product Description
The Arduino Uno R2 is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

I received a counterfeit Arduino with a Sain Store business card enclosed, which I returned unopened. These are clones that are made to look like official boards, and DO NOT MATCH the image on the web page. The thing that bothers me is the web page for this item says "Official board made in Italy". This is why I bought it, but it is false.
They will just end up giving the Arduino Project's work a bad name, and I cannot support them. I did not receive a surface mount board like others have. Clones are perfectly legit, but it is wrong to pretend to be an official board and not have a manufacturing location marked on them, and then cleverly alter the official Arduino markings to say "Designed in Italy" instead of Made in Italy.
As an aside, it wasn't the latest revision R3, but an R2 board, but at least the web image was an (Offfical) R2. Just buy an official board. Support the good work of the Arduino project.

The uno I received from Sain Store works fine and I have no intention on returning it. That being said, it was not an authentic Arduino UNO, It was a clone with significantly different markings on it. (# to denote pwm instead of ~, lower res printing, not in arduino box, does not say "Made in Italy". It is most definitively a clone, if you don't mind that go ahead and get it, but be advised it is not a genuine arduino.

Be warned.
You may not receive what you paid for.
I ordered this unit and received a lower-priced Arduino with a surface-mounted microprocessor, not the far larger microprocessor shown above that is mounted in a holder and so can be replaced by other microprocessors.
There was no explanation of this action by the supplier.
I posted a one-star review, but this seems to have been removed after a sly "comment" was added suggesting that it did not belong in this section because it was not a comment on the quality of the item I received (a real Catch-22! presumably from the supplier).
So make sure that what you receive is what you ordered.

This is amazing for the price.
Compared to what you find at most retailers, this is the best deal you can find for a Arduino UNO R2.
Sure some say that it 'may' be a knockoff. Read more

Get your nerd on.....
I was looking for a cooling solution to an electronic device.
The arduino offered me what I was looking for and at a price that couldn't be beat.

Order from Kingkongmall and you'll even get a USB cord!
I gambled on this guy with all the mixed reviews. Since I'm late to the Arduino game, a lot of the Rev 2 boards are no longer in stock. Read more

Great device
There is sliced bread and there is arduino. Great platform. Leaves me wishing my programming courses in school had better prepared me for this. I am not a programmer.
