One of the 5 pieces worked
Three wouldn't respond to i2c commands, one responded, but kept changing the i2c address. Fortunately, I was able to return them, and all 5 of the replacements worked.
R**C
100ma is incorrect current rating
The correct per channel current rating is 10ma per the OEM datasheet.
