I will always have a difficult time deciding to buy a new hardware from Google (maybe except Pixel phone because I have read some good things here and there on HN about it and my wife have been using it for about six months now and does not have a major issue so far although she said the UI is really confusing/annoying at times) after buying two Google home minis at two different times only to end up with both only being half-functional after just about a year of light use. Good: I have Echo and I can tell that the AI in Google Home (mini) is more advanced than that in Alexa. Bad 1: Every time my wife (who uses Pixel phone) and I (I have an iPhone 6) connect via Bluetooth to our Google home minis, it drops after a few minutes consistently even when we are using YouTube, which is Google's own app. We tried all kinds of ways that we can find online to reset these Home minis, and still that connectivity issue still persists. That went on for about 8 months and now, both of these minis (bought separately 3-4 months apart) are no longer connectable through Bluetooth. I really wonder if other Google Home owners face the same issue. Bad 2: Google Home app is very confusing to use. Another bad example is--I have the temperature metric set to Celcius (I grew up in a non-US country) and both of these minis no longer read temperature in Celcius (after reading it for about the first six months of use) despite how many times I attempt to reset it in the app connected to my Google account. I don't know if it has to do with the firmware upgrades or the app upgrades that has failed to update the parameters within, but even as a relatively tech-savvy person, I still have trouble understanding the UI and worse, how to get these minis do such simple thing as reading out temperature in the metric that I want to use.
