Striiv Bio - Activity Tracker and HRM

Options
Does anyone here use a Striiv tracker/hrm? (https://www.striiv.com/)

I've been using a fit bit for a while now, but I wanted to get a HRM too and the fit bit models were very expensive to the Striiv. I ordered one online and should be getting it this week.

If you have one... do you like it? Does it measure accurately?
