There was a problem filtering reviews right now. Please try again later.
Also, the pins are standard header pins which are a little too short so the board slightly touches the power jack and do not fit snugly. The board actually falls off of my SMD Uno.
Honestly, you are better off buying a protoshield and soldering your own LCD to the board- the circuit is documented on the arduino website.
Edit: I figured out by cutting the trace of D10 to the transistor, you can bridge the cut with a 1n134 or a 1n5819 diode (I used a zener since it is what I had on hand). The 1n134 is hard to find but will allow PWM brightness control without burning out your Arduino. On the other hand, the zener sets the display brightness around safely to full. I updated the rating to 4 stars because of the price.
The device included no documentation at all. I was, however, able to find a website  that documented the shield adequately. Using the provided documentation, I have had no difficulties getting the necessary functions working.
* Disclosure: I was contacted by the company to review this item. They have not compensated me for the review nor promised to do so and the contents of the review are not influenced by their request.
Amazon - Please do not require comments if none are necessary.
By replacing the on board buttons with wired external momentary buttons and reprogramming the functions, this unit has become the visual interface in this new unit.
Will be buying more as projects continue and for an order for 50 more of these test fixtures
