10 Reviews for R4 Smart Ring

  1. Outback in Idaho

    Did not function as designed, and website did not offer any support. Think it is a fake.

  2. CrazyJoe420

    The ring was supposed to be the most up to date smart ring available I use Samsung s20 ultra??? but it was horrible it couldn’t even get an app for it nd neither the directions made no sense.. also its huge x20 and wouldn’t connect!!! Ide say dont buy! XxX good refund policy tho 😉

  3. MSS

    So happy I got this!

  4. Captain my Captain!

    Still trying to figure out how to use the ring. Instructions not the greatest.

  5. Cass

    I purchase the ring for a women very heavy.

  6. Lee

    Ring looks and feels great. Stylish way to access my job security entrance.

  7. Owen Sweeney

    Beware. Totally false. This doesn’t work at all with iOS as expressed in the ad.

  8. Kathleen G.

    The ring is everything I expected. Purchased a size 10 and it fits. Works great with my Samsung Note 20 Ultra. My wife thinks the ring is too big for my finger but I love it!!!! For the price I will buy it over and over

  9. N. Palmer

    I use this exclusively for the ID (T5577) function. With the R3, you had to rotate the the “ID” part of the ring to the top of your hand so that it could be picked up by the reader. The ring rotates on its own during normal wear so each time you went to use it, you’d have to find and read the very tiny text which is a pain.With the R4, the entire front side of the ring contains the ID antenna so it will work in any position. Furthermore, at least with my reader, it works if the ID face is not outward. Meaning I never have to think about wearing it a certain way to be able to use it–a very nice upgrade!The only downside of the R4 over the R3 is that it is a bit larger and heavier than the R3 (#11 R3 & R4 in pics).

  10. James Higgins

    Ridiculously bulky and makes you set up a what’s app account to use.
