Barometers only function properly when your altitude isn't...

Barometers only function properly when your altitude isn't changing, thus, how could the storm alarm function when you're ascending a peak? I suspect that this product description might be a bit misleading - the storm alarm should work nicely when you're at camp for some time, but not while climbing (a GPS/barometer, however, could be capable of this as it can determine your altitude independent of air pressure).

When a storm is coming, the pressure will drop much faster than you could generate due to hiking uphill. Altitude change on foot actually changes the pressure quite slowly.EDIT (by Jersey Hiker): I think you've got your facts mixed up here (see my next question). If my research is correct, it's just the opposite: barometric pressure changes as a result of a storm are typically much more subtle than air pressure changes due to altitude change (assuming we're talking about 1000s of feet).
