I just wish it wasn't so god damn janky. Data sync is a bit of a crapshoot, I often have double recordings on workouts in gadgetbridge or completely missing workouts in gadgetbridge.
No a drawback would be a minor nuisance. You can live with a drawback. That would not be a minor nuisance and definitely not something you could live with.
Slamming the brakes on the highway because either map data is incorrect, it misread a sign, or GNSS is misplacing the car is not a drawback, it's a massive fucking safety hazard.
IMO life is just too short for bad filament, I'd rather pay 5-10$ more for a roll of filament and know that I'm not going to be spending hours and 1/3 of the spool on debugging and failed prints.
IME consistency across batches is almost the most important thing. Some brands print better than others, but none is best across all types. I have 3-4 different brands that I have dialed in and trust to perform the same every time and I stick to those. Buying cheap aliexpress filament is a crapshoot every time, even when sticking to the same brand. Sometimes it works well, sometimes it shortens your life by a decade due to frustration.
I've found the 6mm thickness is perfect for my hands, granted I have a medium-sized male hand and not a huge grappler. 10mm thickness is a little too thick IMO for a nice feeling, but not a deal breaker. The very small screen is a definite deal breaker for me though.
Damn, at 10mm thickness that's a chubby little SOB, nearly twice as fat as my leaf 2. And with a tiny 4.26" screen on top of that, yikes...I love my 7" screen, I'd hate to read on a screen smaller than that.
