"I am a power lineman, so I needed a rugged watch that could get banged around, be exposed to energized high voltage, and very harsh conditions. The TREX has worked flawlessly through all that."
"it’s super durable. ... The watch clasp has gotten scratched up but the face is still fine after nearly a year of climbing inside with it. ... instinct is very durable"
"tanky ... Only thing you really lose is a touch screen but that's better for it's ruggedness and water resistance."

"the battery lasts 2 weeks, that's with 5 days worth of tracking runs and day to day use. Incredible."
"16 days battery life on my fenix. ... The other aspect I really appreciate about my fenix is the battery life. 16 days or so. With everything I have to change these days (laptops, mice, keyboards, headphones, watches, phones), I appreciate not having to worry about it too often."
"Oh, and the battery lasts days even when exercising a lot (weeks without excercise)."

"Full watch-based navigation and mapping features—found particularly on the Forerunner 970 and Fenix series—include offline maps, turn-by-turn navigation, and visual guidance. ... For everyday runs on familiar routes, they matter less, but for trail running or hiking where orientation is crucial, they’re invaluable. ... Maps offer extra value for safety, route planning, and are also popular among cyclists and those exploring new routes"
"Battery life is super important to me. I do ultras so having 24+ hours of gps is necessary."
"Trail running so I can load the route onto my garmin and navigate without carrying phone for 50km"

"The HRV and stress is not gimmicky in fact it was the heads up for my sister in law being diagnosed with cancer …her stress was screaming with no other really identifiable reasons (in 2022) ... in my case my stress was exceedingly high … for months & months and I kept having warnings and then I completely crashed with full on burnout ... Post my hysterectomy I saw crazy stress again ( not as bad as when I burned out but pretty intense) for the first 6 weeks & then it improved a little but it’s only come back to a normal place post 12 weeks & energy levels too only back to normal at 5 months …I didn’t have keyhole. But all that data correlates with the recovery pattern for major surgery & the fatigue was chronic for weeks ... the stress marker was defo the alarm bell for my sister in law and was indicative for me."
"I've taken it on a 2 day 100km ultra marathon, with full GPS throughout, and it was fantastic at tracking everything and still had battery by the end!"
"What I love most are the customizable data screens. ... I’ve tailored the cardio profile specifically for my workouts. ... For example, in a “CrossFit Rounds” workout, I’ve set it up so I can track laps during an AMRAP and see if I’m going faster or slower than the previous round. ... The customization options are endless."

"I have KEF Q150 with a 150 euro amp. They sound drastically better than a Sonos Move 2. They're different products but for the same price you have way better sound, it's not even close."
"costing $1000-$1200, respectively ... can't, in good faith, recommend a high-end Garmin to anyone who isn't rich"
"Addressing the Move, it’s a nice speaker and overpriced for what it does. ... I feel $250-300 is really what it should cost. ... If I reviewed it, it would get hammered on its value."

"During runs and activities, the Garmin watch cannot maintain bluetooth connection to the Airpods, and music starts cutting out. It gets resolved temporarily by pressing play/pause in the Spotify app on the watch, but the connection will cut out again within 5 minutes. I've searched Garmin forums and found that this issue has persisted since the Fenix 6, with no indication that Garmin plans to fix it. The #1 feature I bought a fitness watch for is essentially broken."
"So disappointed with its software. ... Have bose qc earbuds thats a top end product but have constant connectivity issues. ... Spoke to garmin don’t know how many times but they don’t have a solution. ... Not even the controls on the earbuds are working. ... I use this feature quite alot and just because of this I wont recommend this watch."
"when i am listening music from my phone: no interface for watch, no next / skip, or the most important the wheel for volume 😂"

"and I'm not getting as good of readings coming out of the optical HRM, leading to a lot of the stuff being off like sleep, stress, HRV, body battery. ... I don't know if the latest HRM hardware is a regression for me or if the chonkiness of the watch on my (tiny) wrist leads to light pollution or what."
"the watch constantly registers my heart rate incorrectly."
"The heart rate sensor (especially for weight training) is terrible"

"many workout functions require a working internet connection via Bluetooth to the phone to operate. ... None of the complex metrics are done on the watch. Not. Even. Close. ... Garmin Connect often requires an active internet connection. It really annoyed me when I owned my Fenix. ... Garmin Connect often requires an active internet connection for many features. I discovered this when I owned one. It pissed me off."
"I miss the smart watch features and being able to leave my phone at home. ... I don't want my Garmin Fenix 8 because it's not connected if I have an emergency. ... The apple watch also has better fall detection so I feel like it has my back more."
"Garmin’s notification integration with iOS is dogshit."
I was in the exact same shopping dilemma as yourself about 2 weeks ago. I opted for the Fenix Solar 47mm. More expensive than the Endruo3 but I didn’t want the larger sizing. I had a Fenix 5 47mm and wanted similar sizing. On a pure practicality basis - Enduro3 is the clear winner. I wear my F8 Solar 47mm to the office, gym, beach and it’s never looks out of place. Personally the 51mm of the large Fenix and Enduro don’t sit nicely under a closed cuff of a shirt. I also have slim/medium wrists, so the 47mm works better for me Just don’t touch the F8 Pro, waste of money . Another really good option is the F7Pro. Personally too, I deliberately at length over the AMOLED screen vs MIPS. As others say the AMOLED feels too much like a device and gadget. F8 Solar MIPS is certainly bright enough and in “gesture” mode, disappears into the background when not “using” Good luck shopping

It is funny to read all the different lengths people have. For me again it is different, I think it has to do a lot with settings and use. Fenix 8 MIP 47mm, last about 17 to 18 days. All smart phone functions are off, only spO2 when sleeping and 5days a week exercises for at least an hour.
I bought a Fenix 8 AMOLED 47mm yesterday and sold my 8 solar 47mm ( it is unusually thick)
Fenix 8 mips 47mm solar Raise to wake w the backlight. 4 hours of gps activities/ week and 4 hours of non gps activities/week. Averaging 100lux/day charge 21 days
Fenix 8 Solar a Little of Training and Health stats configured. 10-14 days.
I love Apple and Garmin products, and I’ve been waiting for the Ultra 3 release to replace my Apple Watch Series 9. Here’s where my AWS9 falls short for me: camping and hiking because of battery, maps and navigation while biking and hiking, and the dynamic running workout suggestions that Garmin has. I can get Fenix 8 Solar for $880 through a discount with my health insurance which makes it comparable to AWU3. Things I like about Fenix 8 Solar: maps, battery, daily suggested workout, Garmin coach, MIP screen doesn’t look like a mini phone on my wrist. Things I like about AWU3: being reachable by my wife and kids while running and cycling, running errands sans phone, love the design, my watch bands will fit, my Apple Music subscription works, etc. I feel like the AWU3 fits my actual day to day better than the Fenix; although, when I do make it out for that couple times a year backpacking trip, Fenix is the clear winner. But on the day to day I mostly am tracking running and weightlifting. And a weekend gravel bike ride. Anybody have both?
Tough decision for sure. I agree with both of you. I also have a Garmin biker computer and Varia lol. Enduro 3 is really the ideal Garmin watch for me - I just wish they made a 47mm variant which I why I was leaning Fenix 8 Solar.
I got mine pretty close to a week ago now. The Garmin express program on PC is garbage, the Bluetooth headphone setup and use is trash too. But once you get used to it it's actually really nice. The insights, the tracking are so useful. I really like the app. I consider the watch screen an afterthought. I wish Garmin sold a bicep tracker that had no screen and only interacted with the app. Then you can continue wearing a normal watch on your wrist.
I started with the Fenix 8 Solar. Hated it right off the bat. The solar feature is a crappy gimmick. I debated between the Fenix 8, Fenix 8 pro with either screen. I decided to go with the best battery life of the 3 which is the Fenix 8.
Actually the buttons on apple watch ultra are far better. The buttons on my new Fenix are spongy crap with no click.
I just bought a Fenix solar last night and so far it's a giant POS. The UI is ass, syncing Bluetooth is stupid, Garmin pay is garbage and the battery life isn't anywhere close to advertised.
Yep. I have an AWU2 and a Fenix 8 Solar. Probably selling the AWU2 soon because it failed me so badly on a recent 70M ultra. People knock the Garmins for their poor smartwatch features, but honestly the differences have really minimized over time. On both watches I can: * use voice commands to quickly set timers and alarms * check the weather, my calendars * respond to text messages with Siri * this is much, much better on Apple Watch, but the Garmin has gotten it done for me, including when I'm going 20 mph on a bicycle or flying down a ski slope * contactless pay The only real advantages Apple Watch have are cellular, a few niche app things like unlocking my Level app, and better speech-to-text/Siri performance. The UI is also nice on Apple Watch, but the revamped UI for Fenix 8 and Enduro 3 is better than before and I quite like it. I'm not apologizing for Garmin Connect, however. That's still pretty rough. The Garmin Fenix 8 really does have a better training/wellness package. Sleep tracking works well for me, and Body Battery and Stress are actionable items for me that Apple Watch cannot replicate, not even with 3rd party apps, and I'm a Bevel subscriber. The AWU2 is a nice to have, but as a guy who does ultras north of 50 miles and long, off-grid hikes, the Garmin is the better device.
I had my Fenix 3 HR for almost 10 years before switching to the F8 Solar. It was still working, not a single scratch on the sapphire glass (used it for rock climbing and in harsh environments). Only replaced it as the battery runtime started to decrease (had to charge at least once a week in the end) and mainly because I wanted the bee features 😁
I've had both and honestly if you have a solar or a amoled set to gesture and not aod they pretty much get about the same. The solar charging is better than on older models but doesn't really make much difference really.
