First time user, it just worked!!!
First time use one of these. I’m impressed on how it just worked with the Arduino Uno R3. I used the internal Arduino library for 7 extra input pins.

8 io lines
I love the interface. Easy io extender.

Works great, but I2c connections are different than the standard I2C backpack , caution
Worked fine, be careful with I2C to backpack connections +5,Gnd Reversed. KArrange KeyPad wires until proper operation.

Most of the PINs are bent
Most of the PINs are bent DO NOT BUY IT

I guess it's fine
I mean it's fine. It's hard to use, it's slow but it's reliable. It sinks current so it can't even drive an LED this is purely for logic level stuff but it can't even drive more than three octo couplers so don't intend to use more than three of these pins at a time. Don't really like it but it's got its use cases.
