It's ok. I expected more. Not a serious athlete but I work out a lot and find some of the features and the app presentation of data quirky and not overly informative. Like during an activity, there is nothing on the screen telling me live time performance. The only thing there is a black screen and the option to stop the work out. And when I open the app and see all these activities that it detected, I can't go in and code what they were (like walking, or working out, etc). The only way to do that is to start the activity in the app. And I'd like to have easier, more intuitive statistics about my day with recommendations more like a whoop or an apple watch. So overall, the unit is nice but the app interface is sort of clunky and should be updated. Lastly, I would have liked if it came with a back up band.

I've been using the Cirqa for several weeks and it has become an invaluable aid. The guidance on sleep as well as the detailed data on many aspects of overall health has encouraged me to adapt my behavior. This is greatly superior to the Fitbit/Google Health which I've used for many years. Excellent!

I received the Cirqa three weeks ago and am really enjoying it. I got it to track my sleep and to measure activities when I am not wearing my Epix. I know my Epix can track sleep but it is larger and heavier and I am very aware of it on my wrist when I am trying to sleep. The Cirqa is a little on the big side but it is very light and once you get used to it, barely noticeable. The band is very comfortable. As expected, it incorporates perfectly into the Garmin ecosystem and I use it with my Epix and 1050. Make sure you select the device you want to use daily and for training in Settings in Garmin Connect. The price is reasonable and no monthly fees makes this a worthwhile data collector.

I'm a runner, run 2x Marathon's per year. Used to have Whoop and Fitbit Air. The Cirqa feels more premium than the others. It is big, i have a small wrist but still feels very comfy. Although the Garmin Connect app has lots to improve to be near Whoop and Google Health app. Will keep the Cirqa just because of the ecosystem.

I do not like it. It battery does not last more than a two day charge. It does not do much. I have had a Garmin Fenix 10 years and it is wearing out. I will just get a new Fenix that is discounted as the Cirqa is not good at what it is alleged to do, does not do much, and does not keep a charge. The Fenix does not even keep my steps well, or my sleep details correctly.

I have been overall happy with the Cirqa-smart back. My one complaint is battery life. It claimed 10 day battery life. I get 3-4 day life before I have to recharge. Went in and turned off all alarms as that is supposed to help, but didn't make much difference. Do love how it syncs with my Garmin app on my phone and don't have to pay a fee for the info.

Bought this thinking it would be minimal and barely noticeable on the wrist. But it is the feels like I have a watch on my wrist, and I am a large wrist man It gives you good metrics but not as much as a watch Should have bought a watch as it feels like I'm wearing one and I would like the extra metrics a watch gives

This device is treacherous. Operating it is difficult at best and Garmin support is terrible. Currently, I'm going to pursue sending it back. I was using it recently and while riding my heart rate kept going blank and I would have to reconnect and restart the device.

I sent this band back immediately. First, I ordered the smaller size because my wrist circumference was in that range, but because the clasp doesn't really come apart, I couldn't get my hand through it. Secondly, I think the sensor device is way too long. I'm sure this will change when the second generation comes out. I'll wait until you get the bugs out.

Pros: can wear a mechanical watch while still collecting all Garmin metrics; comfortable and light weight. Good to have a biceps band option; button to start/stop activities and alarms; reasonably priced. Does everything I expected. Cons: software is still very buggy; band attachment method is not well-engineered - it's too fidgety. Module is larger than competition. Garmin sleep tracking algorithm could be better (this is true across Garmin devices). I expect the software bugs will be resolved with time. 2nd gen Cirqa should consider a different way to attach band as well as reducing the module size.
