Finis's dedication to quality has come through in this goggle. I have been using them for a year now and love how I get immediate feedback on lap, set and rest times. The uploading works flawlessly and is just downright cool. The workout uploaded it provides is really helpful and helps me plan my next workout. The only improvement I would make would be to add a Heart Rate option so I can tell if I need to speed up or slow down when doing pace work. Buy these goggles and you won't have to keep track of your yardage because it shows you how far you've gone.

I got them as a replacement for Gen 1 and I regret the purchase and think this is a step back from the previous model. I regret buying it.
-- The space for the pod is somehow much larger than in Gen 1 and I have to slam the button with everything I have to start/stop the workout.
-- The Gen 1 model had amazing visibility and I could see my lane mates without even slightly lifting my head. This model has a decreased visibility. If you swim with masters, losing this feature is a big bummer.
-- This is larger and won't fit smaller faces. I'm a woman with a small face and look like an alien.
