the ring is fine and it works but after a few weeks of wearing it just came apart so don't bother buying it.
Thank you
Super !
Good, just measure your finger carefully!!! It is working pretty good BUT only near the readers and by near i mean very near even touching that is for the 13.56 mghz the 125 khz is working good enough.
that's probably a 5 or 6th my jakcom ring... it's very fraggle (
It is a really good product and works
Rfid 125mhz is writing very nice with fliper zero. NFC i can’t write my card. Dimension is bigger. Right side.
Just as ordered, fast and nice service, a bit large not i size but in shape
I haven't checked it yet, I need it in size, I have a smaller size
All as described
Everything works fine, except for a long time. But the price tag is an order of magnitude lower than other rings. This is the third ring that I ordered myself. Others broke. The quality is not very good. Ceramics are cracking. But, if you wear it, it will not break for a long time
Everything OK, according to the announcement.
