I got an email from pleoworld support when I sent a message regarding battery life problems:
There is a simple way to distinguish between Ugobe Pleo or Innvo Labs Pleo by checking the serial number, the 12 digits serial number of all Innvo Labs Pleo is formatted as 8168XXXXXXX8 . The serial number is found on the bottom feet of Pleo.
So the Serial number’s are: 816800000018, 816800000028, 816800000038.................816800005998, 816800006008, etc, etc. These are the NEW AND IMPROVWED INNVO LABS VERSION PLEO’S.
