Banggood

No sé cómo funciona.

is not good i dont like it

Size of ring is a little larger than ordinary one (10 is rather like 10.5 than 11)

Good product just a per image, though no user manual or how to use quide.

Recueved my ring after 12 days of order which is very suitable. Overall NFC features work fine and it is a good ring in this amount. Although it looks very big in size so i would recommend anyone buying this ring to order the size that is one number less than your actual ring size. One thing that can be improved is the shiny outer surface of the ring. It can look much better if the surface is made a little dull. Thank you.

same as described i like it

it is working good but few more mobiles only

great gadget, progamming worked, is recognized by most devices. a better reception would be better, you have ti put it really near to the reader, usage with an mobile phone is not very easy, you have to find the exact positioj to get it work and the memory is not big enoght, 4k mifare would be great. because of the low memory i can not use this ring with my door.
