FR 945 - no Updates since months?

You are a perfect customer - buy another product from the manufacturer with basically bad product support?

Why not moving to polar or sunnto?

Agreed. Only a few owners complain that their units work far from perfect with 4.40. However, if mine and others work just fine, probably it is not SW issue but HW. I had a problem with baro altimeter - it failed to measure vertical gain (I estimated that errors were beyond +/-10% range - e.g. I ascended 600 m but 945 showed only 530 m). I thought it was a SW issue, since the problem occurred just after the latest update. I reported this problem to Garmin, and to my utter surprise it decided to replaced my 945 with a new unite. Since then, it works just fine. Of course, it would be nice to obtain some new functionalities (like some sleep widget, or climbing/bouldering app which is present on F6), but from my perspective it is not essential and it doesn't change my opinion on the product. 

That's exactly what I thought... bad product, bad support but hey, I will buy your even more expensive product because I am not satisfied... 

What is bad product support? You have a faulty unit, it gets replaced. Bugs are fixed. The only real issues i'm reading about are ohr (life sucks, it is what it is) and weather data (not having those issues on android 10). But pure software (eg never ending power meter calibration, watch face lag etc) issues are eventually going to be fixed. 

Neither Polar nor Suunto offer the same amount of features as Garmin does. Overall - my opinion - i'm quite happy with product support - my biggest complaint is the amount of time it takes to bring the new features that the F6 gets to the 945.  

Lack of updates, high battery consumption, faulty altimeter. Others may/have other issues, those are mine.

Replacing a faulty unit is, in my opinion, the minimum.

There is an issue also on Garmin Connect w/ my Android 10 phone, already reported, Garmin said it is a bug but there is no timeline to sort.

Never had a Polar. I do have Suunto dive computer and support has been good so far. Planned to replace ir for the upcoming MK2 but not sure after the FR945 (FYI had 620, 630, 935 and now the 945 and the 945 is the first I am not satisfied with - already replaced from Rev A to the latest one due to the buttons issue at the early days btw)

While I'm disappointed in the software support of the 945, what keeps me is the Garmin ecosystem.  I'm in a large running group, and we all have Garmins...  challenges and such are a lot of fun.  Trust me, I'd love to check out Polar or Suunto at some point. 

As ex-user of Polar's products - trust me, Garmin support is superior (unless Polar changed its policy lately). Polar has very nice and clear web platform, i.e. PolarFlow, which is - in my opinion - clearer and better designed than GarminConnect. I do remember that it took some time for Polar to fix bugs in its once top model, i.e. V800 - it was really frustrating waiting for updates, fixes etc. Finally, V800 became excellent and mature watch, but it took ages and Garmin made in the same time a huge leap forward. Personally, I think 945 is a complete watch - there may be some minor issues which update can solve, but all this cry about battery, OHR, baro, alti seem to be results of faulty hardware or (in some cases of  battery drain) using second-party watch faces, for example. What a user of 945 may wish for is that Garmin keep updating 945 with features which are present in F6. 

It's a bit rough to state "my watch works, so there can't be any software problems, it must be related to hardware". Especially as there are different ways how people use their watches.

If you just use your watch to check the time and record a run from time to time and you are happy if you see some recorded heart rate and track afterwards, you will be tempted to say everything is fine.

But there are others who use their watch in a more advanced way, pairing sensors to it deriving several metrics during their runs and who rely on exact data. And if the recording of that data fails sometimes or is incomplete, this is terribly annoying and certainly not a hardware problem.

Same goes for OHR readings, if the OHR algorithm fails in certain situations while it works in easier scenarios this is not an hardware issue but a problem with the software.

I just mean that people who want to use full functionality of their watches in an advanced way will run into the reported problems more frequently rather than users who only use the basic features or do not pay much attention to the reliability of recorded metrics.

Agreed.  The F6 got a massive update (two?) weeks ago, and our watches which are identical hardware-wise have seen nothing.  And thanks for the info on Polar; their watches and Suunto's both look very nice, but, I'd be on an island over there.  That said, if Apple ever got their crap together and put out a true sport watch with a Garmin-esque battery life, I'd try one just for the heck of it.  Software support is definitely not an issue with their products.  I had a gen 1 Apple watch and it was awesome, but mostly useless for long distance running training.  Also, touch screens on running watches are a terrible idea for several reasons.
