Okay, so I've been wearing this Garmin Forerunner 955 for about 3 months now, and holy data overload! Coming from an Apple Watch, this thing feels like switching from a tricycle to a Tesla.

The battery life alone is witchcraft - I charge it maybe once a week? Meanwhile my Apple Watch needed daily charging like a needy ex. The touchscreen works shockingly well (even when sweaty), though I mostly use the buttons because #musclememory.

Training Readiness Score is my new obsession - it's like having a tiny coach on your wrist telling you when to push or chill. Though fair warning: it might humble you when it suggests Zone 2 runs slower than your grandma's walking pace.

The race widget is pure magic. Tell it your goal time and it'll pace you like a digital Sherpa. Probably shaved minutes off my last 10K thanks to its nagging (I mean, helpful) alerts about being ahead/behind pace.

Downsides? It's chonky. As someone with wrists smaller than most toddlers', sleeping with this feels like wearing a hockey puck to bed. Also not great for quick text replies - miss being able to send heart emojis from my wrist.

Final verdict? If you're serious about training (or just love staring at metrics), this watch turns you into an instant athlete. Just maybe don't wear it to fancy dinners unless you're going for that 'cyborg chic' look.
