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

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).

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