Fun story: when I got my Withings watch 5-6 years ago couldn't get it Bluetooth paired with my phone. Contacted support.

Me: hey bluetooth pairing isn't working I've tried A, B, C and here's additional context. Withings support: [over 24 hours later] Have you tried A? :) Me: ...Yes? Withings support: [over 24 hours later] Have you tried B? :) Me: As I said initially, yes. Can you please batch things to try to expedite this since replies are so slow? Withings support: [over 24 hours later] We have to do this in order. :) Have you tried having a different phone even though your phone meets our listed requirements? :) Me: ..................... Me: I debugged it myself in Android dev mode and got it working, I had to do X, perhaps you can relay the issue to your engineers. Thanks for nothing. Withings support: [over 24 hours later] oh

And as a bonus after an update a couple years ago it looses track of time within a couple weeks and has to be manually set.

Very pretty product once upon a time with horrid customer service and software.
