A:AnswerDo not wear for water aerobics! It is water reisistant not waterproof I accidentally wore it for 2 seconds wading and it needed to dry out for an hour before working again
A:AnswerNo, this product is not intended to be submersed in the water. You can use it to shower, as it would not be submersed in the water, but I would not use it for swimming, doing the dishes, etc.
A:AnswerI have a galaxy and it syncs easily. I normally need help with setting up tech stuff, but this is very user friendly. I did it without instructions is was so easy.
A:AnswerYou can swim in the Flex, but I would only recommend swimming in a pool and not a lake. My son lost 2 Fitbit Flex swimming and playing in a lake. Also, Fitbit recommends making sure that you take it off and let it dry later. You cannot swim with the Charge or the Surge.
A:AnswerAbsolutely. Though if your looking to monitor your heart rate the flex model does not offer that feature. You would need to get a Fitbit HR or better to do that.(you wouldn't have an issue with these either)
