Really impressed with the Lumina Tag. I bought it mainly for festivals, and it was brilliant.

I used it at a festival with a group of friends and, for once, I never lost anyone! Being able to see where my friends were made meeting up in a huge, busy crowd incredibly easy, without constantly relying on phone calls or messages.

Setup was really simple too. Linking it to my phone and then connecting with my friends took hardly any time at all. The Apple Watch integration was an added bonus and worked perfectly — I could check on the group without even needing to get my phone out.

It’s one of those products that you don’t realise how useful it is until you actually need it. After using it at the festival, I wouldn’t go to another one without it.

Highly recommended!

We used Lumina during Monterey car week when text and phone were spotty due to large crowds at major events. Lumina allowed each of us to explore different sections of the show and easily find each other.
