I'm considering one of these specifically for the claimed 120 hrs battery life in Ultra mode (GPS tracking still enabled), but I'm having difficulty finding any reviews that confirm that figure in real-world use?

All the reviews when it was released last year - even dcrainmaker who is extremely thorough - talked about the 'claimed' 120hrs, and I figured after 6 months people would have had chance to put that to the test, but as I say I'm not finding much online.

I have a Fenix 3 HR already, but I'm doing an event later in the year where I want to track and record to GPS and if I took the Garmin the battery would need daily charging. I can't take a power bank, so hoping the Suunto 9 will fit the bill..
