HelioCore
My overall experience is very good. I liked how I can buy the Helio Core on its own and I don’t have to buy the whole device with the charging pod and strap again, as I ruined my first device during an MRI session.

It's an amazing device, I've been using it all day for 8 days now, I train 3 times a day so I found it perfect.
