A:AnswerHi, there. Per our Terms of Service, all Fitbit Premium payments are considered final, non-refundable, and non-transferrable, so you'll need to purchase a new subscription for your wife. For reference regarding our terms of service, visit: https://www.fitbit.com/global/us/legal/terms-of-service#fitbit-paid-services For any other concerns, reach out to our support channels at: https://myhelp.fitbit.com/s/support?language=en_US
A:AnswerI just got a Sense 2 and I love it so far. Don't get a Versa 3 if you're using to track active minutes and heart rate while exercising. It is not accurate. My Versa 2 was far more accurate than the Versa 3.
A:AnswerYes. We have had problems with the sensor when we exercise because the watch malfunctions if you sweat. We have already returned one and are going to return another. Dissatisfied with this product.
A:AnswerThe Fitbit+ subscription is optional. The watch comes with six months free. After that it is just 9.95/month. I personally think it's worth it but one could easily survive without the subscription or start and stop it as needed.
