Battery is no good. Ten days? Not even close. Four days at the most. I may only keep it to give my Fenix 6 a break but I am seriously considering returning it. Will not recommend.
I’ll caveat what I’m about to say by stating I’m still getting used to going screenless.
I’m in the Garmin ecosystem. I currently wear a Epix2pro, a Fenix 6 for years before that, and I also currently use a Garmin scale, bike computer, etc…
For my use case, I wanted a screen-less wearable so I could wear my mechanical watches more. The Cirqa seemed like the perfect answer and it still kind of is but mine has one flaw which is a bit frustrating.
For me, the Cirqa on multiple occasions has not tracked my sleep at all. It tracked my HR throughout the night but not my sleep. During a typical week, it’s been doing that 2-3 days out of the week. That obviously affects every other stat, so that’s something I hope Garmin fixes soon.
Good technology, good implementation, still debating the best use for it. I have a FR 970, that is a great tool for my running, cycling, other exercising. I wanted to be less dependant from it and go back to wearing regular watches and keep tracking my vitals. This was the primary use for the Cirqa. Does it worth the cost? Maybe. Using Cirqa during my running or cycling is not an option: I need to monitor my activity while doing it and a screen is essential. Garmin may have other otions for its use in the future, hopefully.
I bought this as a complimentary device to my Fenix 8 and now 9 Pro. I love that I can leave the Fenix at home on occasion and still keep all of my health metrics tracked. So far the swapping back and forth has been seamless.
I have been using it for a few weeks — relatively short battery life. You can record an activity but the data is not robust - ie. Calories and time only - it does not record your blood pressure like the Hume band does
