Not bad for that price.
After spending some time to hunt down the correct library that works with the IIC module, the LCD works good, except the line wrap going from line 1 to 3 and 2 to 4, I guess those 4 line LCD do that after searching on google.

Inadequate shipping material, no documentation, oh, and it's defective.
This was a disappointment in every way. The thing came shipped in a plastic bag. There is no documentation, so you have to run code to sniff the I2C address. The pot on the back for brightness covers off to full brightness in about 10 degrees rotation. To top it all off, after spending a few hours trying to figure out what was wrong with my code, I figured out it wasn't my code, it was the defective LCD module.

Works great and uses few pins
I have this working on my Arduino Leonardo and it's great! The I2C communication allows the entire display to run with only two wires to the arduino. I used the liquidcrystal_i2c version 1.2.1 library available elsewhere online to run it based on their examples.

Junk
Junk. Wasted 6 hours trying to make it work! i2c module was OK but the display never worked properly. Bought another one from a different vendor and that one worked right out of the box.

Five Stars
Works great and easy to use (yeah make sure you get the right library!)
