    I jumped with this altimeter only 3 times, but fall in love with it!
    Sounds good in a plane, free-fall, and under canopy.
    Accidentally bought two subscriptions. Wrote email to support and they cancelled both payments and sent me a video on how to enable free subscription (super friendly and fast responses from support). Also I believe that it supported by the guy who created YouTube manuals for the Alti devices (Casey).
    The most what I like in this devise - it's not need to turn it on/off. Just put it into the helmet, charge once in two month and enjoy!
