Good value but pins are tight

The module works as advertised. My only complaint is that the header pins were a bit tight to solder, but once connected it works great.

Essential module for mixed voltage systems

If you are working with both 3.3V and 5V logic, this is a must-have. Bidirectional shifting works flawlessly on the SDA and SCL lines.

Does the job

Solid little board. I wish it came with male headers included in the package, but otherwise no complaints about performance.
