    Amazing BUT.,.

    The new oura ring is amazing, I’ve had it over a week and it hasn’t scratched, only charged it once, and looks amazing. HOWEVER, it has no weight to it, its so thin it’s impossible to believe there’s something things inside. If you have and apple watch a garmin, a fitness tracker ring, GET THIS INSTEAD!

Questions & Answers

  • I have a oura ring 4 and i have the 2 year warranty. If i wanted to get the oura ring 5 since my oura ring 4 is scratched is there a way to exchange that or how does that work?

    It 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.

    Answered by Joesap

  • What finger should you wear the ring on, can it be any finger?

    The pointer finger of your non dominate hand

    Answered by NANCYP

  • Do you have OR5 ( 2026) with white or blue color?

    No, unfortunately. However, some after market vendors offer ring covers, protectors, and jackets to suite a more personalized touch.

    Answered by Ladynblq

  • How do you get the sizing kit?

    You 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.

    Answered by Ladynblq

  • Does the oura ring get scratched easily?

    I 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.
