You’ll be probably be happier with a higher quality watch than with one that barely works. I would not recommend going for an option because it’s cheap, instead go for the one that’s good enough for you needs.

No need to buy the same one as I did, but I have been very happy with my “not the cheapest, not the most expensive”-garmin watch for years. It is reliable, does what i need it to do and is not so expensive that i am afraid of breaking it for instance. I did need to make choices to be able to get it, i could not spend that money on other things, but that only made me feel better when I got it.

More on topic: it’s easy to find accesoires/replacement parts for my watch, it’s easier to get it repaired, both at garmin as well as a local shop, the software has a lot of integration option with other software (strava, komoot, etc.) and i can download apps and watch faces other people with the same watch built and i can be sure my alarm goes off in the morning. I don’t expect the temu watch to have these things. For me it was worth to pay a bit more. Sidenote: I did get a screen protector for my watch from AliExpress, so apparently I’m not against that 😏
