As is well known, going back four years on the forums, water or sweat will disable the altimeter on the 530/830 Edge. Garmin is well aware of this, and as far as I know , continues to sell units with this defect. The first time it failed on me, they replaced it free of charge. However, the replacement had the same defect, failed, and now they want $140 to send me another defective unit. If these are advertised as water proof, would this be a FTC violation?
