Scanwatch Pros and Cons

Pros:

1. Smart design concept: the device is not bloated with unnecessary softwares or features already exists in mobile phones and this reflect on ->
2. Amazing battery life
3. Quality materials 
4. Beautiful and classy
5. Automatic activity recongnision (swimming, running, biking!!)
6. Helth Mate app teach the user and suggest articles  for reading based on users data

Cons:

1.So many terrible bugs :

• The calories during workout is always totally wrong in the watch.(firmware 1751)
• The battery show 100% for many days without chaniging then start to drop fast(firmware 1601) seems that it's solve not sure (firmware 1751)
• Rarely the device show wrong arterial fibrosis warning when I am not wearing it.(firmware 1471)(not clear if firmware 1601 fixed this). I never encountered this again ((firmware 1751))
• Heart rate accuracy has big question mark (https://www.youtube.com/watch?v=80xqCjEL69w)(firmware 1471) now it's way better or fixed (firmware 1601). Even better in firmware ((firmware 1751))
• The watch get wrong sometimes when the mobile bluetooth is off (firmware 1471)(not clear if firmware 1601 fixed this). So far it's working fine (firmware 1751)
• SPo2 sensors accuracy might not be sufficient according to recent test (https://www.youtube.com/watch?v=80xqCjEL69w)(firmware 1471) (not clear if firmware 1601 fixed this) (not clear if (firmware 1751 fixed this)
• Unreliable sleep tracking according the test (https://www.youtube.com/watch?v=lWPxpdUjLBI) (firmware 1471)(not clear if firmware 1601 fixed this). I think it got better after updating ((firmware 1751))
• The watch can't detect all biking activities specially the short ones (it will show cycling activity only if one cycle for 9 minutes or more(firmware 1601). Not sure what is the status now didn't cycle since long time ((firmware 1751))

2.Poor customer service 

• Poor relationship with customer. This forums is full of complaints with no one from Withings taking care and time to reply or comment on the posts
• Early adopters raise so many concerns yet the device went to the market without fixing many of them. Things are getting better now
• No one know what they are doing except that they are working hard according to them to fix the problems
• No one know what features they will add or what bugs they will fix
• No one know the details of the features  that were added to the previous updated firmware. Only shallow information given about firmwares

https://support.withings.com/hc/en-us/articles/360010670098-What-s-new-with-my-ScanWatch-

• They don't address the problems and explain the reasons for these bugs and why they send the product to the market with all of these issues (i.e. obvious wrong calories calculation) without being clear about these issues!!

3.analytics or smart features could be better:

• The device is more like data collector i.e. no body battery, stress level, recovery time, train more , train less, relax now, training effect......

This watch is getting more care from Withings and things are getting better by time.  It would be nice if Withings address the limitation and problems in their watches and tell the users when it's going to be fixed. (calories during training is waaaaaaay off) It is good for the trust to tell what are you intending to do and share your development plans.
