A:AnswerIt honestly depends on your bestbuy staff. Some may take it back and charge a restocking fee to return the item, and refund you. Others will only offer to give you the same ring at no cost since you are on a 2 year warranty. Technically it only covers the replacement of your Ring 4 with an identical ring 4 but it doesn’t hurt to try! Worst they can say is no.
A:AnswerYou can order from Bestbuy or Oura. I would suggest using the sizing kit vs the metal try ins in the store. The sizing is extremely off with the metal rings. Another alternative is going to Best Buy and asking a staff member for their test kit and they’ll let you use it to find your size.
A:AnswerI believe that depends on the design you get. I have the brushed metal specifically because I didn't want to see smudges or scratches on it. I've had mine for over 2 weeks now and wear it on my dominant hand and no scratches so far.
A:AnswerMy wife wears it on her left index finger (same side as her wedding band, so her ring finger is already occupied. I believe the index finger is the finger the company most recommends for most accurate metrics.
