This watch is great! I was tired of my Fitbit watch dying on me at work during the day, so I researched and found this watch and the lifetime of it last more than a week. Charging time is within 2 hours and the accuracy of sleep and steps. I recommend this watch if you are active at work or sports

Here's my feedback after 2 years with this watch. In short, the good part is the amazing battery life, the light weight of the watch and the load of features available on the watch, including the online training hub.

Pros of the watch itself:
1. It is very light and convenient for wearing, even during sleep.
2. It has an amazing battery life. I used it for 12 whole days between charges, wearing it all day long, with ~40 minutes of daily aerobic activity, which was mostly indoors (very little GPS usage) - and even then, it still had 10% battery when I started charging it. At 10% it starts asking to be charged.
3. It has a great always-on display, which is very clear even under direct sun.
4. It has very good GPS.
5. It connects very easily and reliably with many bluetooth devices, and due to its amazing battery life, you don't have to worry about this bluetooth connection taking too much battery (compared to my previous sports watch - Xiaomi Stratos).
6. This is a matter of personal taste, but I love the crown button interface. Works great!
7. The configuration of the various workout data screens is awesome! You can configure multiple screens for each workout type, which you can scroll between using the digital crown button, and up to 6 data pieces on each screen.
8. The amount of features available on the watch! And recently, it's been added breadcrumb navigation. It doesn't contain maps, but the breadcrumb navigation works amazing and enables you to follow the route easily.

Pros of Coros support / app / website:
1. Coros support is great! They frequently provide updates of the Android app and the online training hub with bug fixes and new features, and also firmware upgrades with bug fixes and added features.
I sent the Coros support team a number of bugs and requests, and they were all fulfilled so far; whatever is not related directly to the watch (app / online site) was usually fixed within a few days, and what's related to the watch itself was included in one of the firmware upgrades that followed. One very good example of that was sleep tracking, which originally appeared in my "Cons" list (because it didn't work for me well), and now works great so I removed it from that list.
2. The online training hub is great. It didn't exist yet when I bought the watch, and went live later on for free. It provides a convenient way to create / update training plans, see your entire training history and statistics.
3. The EvoLab metrics is great, and provides some derived statistics about the efficiency of the training and the readiness to easy/hard training.
4. You can now design routes using the app and upload them to the watch.
5. A great new free service was launched (for Coros users), I think towards the end of 2022 - "Coros coaches" - where you can consult with certified Coros coaches about the training plans and how to properly adapt them for yourself.

Cons of the watch itself:
1. The built-in heart rate sensor is only good for activities where the heart rate does not change rapidly. If the heart rate changes rapidly, it may take some time for the watch to catch up on the change - so it is not reliable for HIIT training, for example.
The up side is - I can make the watch use the chest strap and then it will report correct heart rate, and as a result also the other reported data (such as calorie count and training load) will also be more accurate.
2. Sports selection and configuration: This is somewhat limited. For example, there's "bike" but no difference between road cycling / mountain biking, there's no "elliptical" (for which I need to use the generic "gym cardio" sport). There's "indoor run", which allows me to select the speed of the treadmill, but this is limited to speeds 3-20 km/h with 0.5 km/h steps between them. My treadmill can only jump every 0.2 km/h, for example I can use 11.4 or 11.6 km/h, but this speed cannot be selected by the watch - only 11 / 11.5 / 12.
3. Using the automatic gesture backlight or GPS activity affects the battery life considerably. When using more of these, I have to charge the watch after about 1 week (compared to 12 days without using much the backlight or GPS activity). Even 1 week is awesome, but it shows the toll on the battery life.
4. The heart rate display itself during an activity is not color coded (according to the current zone); you can configure the watch to show half a circle with colors according to heart rate zones, with an arrow pointer that shows you where your heart rate is within that circle, but this only works if you display up to 4 data pieces on the workout screen. If you display 6 data pieces, you don't have this circle and no indication of the heart rate range.

Cons of the app / website:
1. The app shows the details from the watch, but it does not provide much feedback about how to improve. However, in the recent year, Coros coaches have started to write coaching articles which explain how to improve using EvoLab. This is a great source for training.
2. Coros EvoLab: This provides a lot of important details about the training, but to get started, it requires some running. I wasn't used to running at all, I was mostly into mountain biking, so this was difficult, but there is no way to activate the EvoLab metrics without the required outdoor running.
This got improved a lot recently (in 2023) but it still requires outdoor running. Previously it required a lot more running to activate.

I've had many running watches over the years, including various models of Garmin, Timex, and Suunto. It's to be expected that each new watch will have improved functionality over its predecessors. However, that improvement usually comes with a hefty price increase. The COROS Pace 2 has the best functionality I've ever experienced, but it's also far less expensive than comparable current watches.

I particularly like the wrist-based heart rate monitor, the first of its kind to provide really me consistent and accurate (as compared to my oximeter) results. I will never return to chest strap HR monitoring, as the current straps, while they may still be a bit more accurate than the wrist, do not last very long (12 to 18 months), require constant maintenance, and are very expensive to replace.

For me, the POD is maybe not strictly a necessity, but it provides a whole lot more usable information about my form and fitness than I've ever had before. I will never run without it again. Even if you consider the POD an unneeded luxury, the total price of Pace 2 and POD is still way below the competitors' comparable cost.

If that's not enough, COROS has the best support organization I've ever dealt with. Many do not address your issues in any useful way; some don't reply at all; none (except COROS) will actually admit that something needs to be fixed. COROS has acknowledged that a) there is a problem with automatically exporting distance in metric units even when you've selected English and b) the reporting of power numbers needs to be improved.

By the way, if you're considering wearing the POD in front instead of in back (in order make certain you don't lose it), don't do it. I asked COROS support about doing so. The COROS support guy did some experimenting on his own and also consulted the development team (have you ever gotten such help?). I also did some experiments and we all agree that your data will be completely messed up if you wear the POD in front.

Nothing is perfect. For example, I'd like to be able to export my POD data in .CSV format for easy insertion into my running spreadsheet. COROS doesn't plan to do that, but they at least told me a way I can accomplish the same thing using .FIT format.

If you're a world-class runner, you can probably find lots of fault with the Pace 2, particularly in the quality of those exotic power numbers. But if, like me, you're just a person who loves to run and wants to be the best you can be, I think the Pace 2 might be just right for you.

Love the long lasting battery, it is very accurate when running and compatible with other Coros accessories as the Pod. Great watch
