I recently replaced by Suunto altimeter watch with an Azio Altimeter. For a third of the price I got a lot more. all the same functions but much easier to use. I really like that the altimeter and heart rate functions have their own separate data logs. And the chest band for the HR function is more comfortable on the Axio. The band itself is a big plus. Always hated the Suunto band. Azio's fits and feels much better without the overlap on the end of the band. The only thing I miss is the countdown timer on the Chonometer. All in all a great buy for the money.
