Very use case oriented review
I like it. 10/10 would read again ;)
Not gushy, not completely against it, but weighing the additional data and analyses against the (in)convenience, the struggles in setting up, and also the "style" of the device. It makes me realise: no, I do not need one. At that price point I am severely tempted to, but then what's the additional benefit (and I don't even use Strava, but simple GPS track recording)? And more importantly: will I make use of the data, and how? Maybe (probably? likely? almost surely 1?) not as much as I might plan to. Same with buying a new bike, sure, it's nicer and quite a bit lighter - but I know that I can easily save twice the weight while saving money, simply by reducing my sweets intake (oooh, nice looking pastries, which are often not as satisfying as they look, so no actual loss!). So: yeah... nah, I'll pass. On the bike and the fitness band.
Good luck with your planned ride! Ride safely!
