14 months later & I still LOVE the Samsung Active
Rating: 5
It was back in early 2019 that I purchased the Samsung Galaxy Watch Active, months later the Active 2 was released. I sold my Active and Purchased the Active 2. Months later, November 2019, I purchased my first Active 2 LTE and then sold my Active 2. Yeah, the Active 2 LTE has been my favorite smartwatch in the last five years!!! Here's my YouTube channel in which I have tested the watch and added VLOG style posts.

Better than my Apple watch 3
Rating: 5
Im in love with this smart watch! Is way better than my apple watch 3. If you are going to buy the Galaxy watch active 2 invest the extra $150 for the LTE version, I bought the regular watch and end up changing it for the LTE version which is PREMIUM in ALL the sense of the word.

Cool Watch!
Rating: 4
Great watch. It has a lot going on. I only hope that an update will eventually allow it to support a trail hiking gps map system. That will make it "whole for me". That was the main reason for me purchasing it. The name "Active 2" made me assume that it would support more gps aps.

Galaxy Active 2 Needs Improvment
Rating: 3
Samsung really makes Good Hardware, But software I don't think so. But Samsung Active 2 Hardware is very Nicely Design, But Software wise is Behind Google Wear OS, I don't like the Tizen Software lacks of Pure Android Apps and the Samsung App Store is really Bad., I come from a Fossil 5G with Wear OS and it had most Android stock apps Like Google Play Music, and a lot of Stock Android Apps, Samsung Needs to End TIZEN and BITZY, and add better specs to its Samsung Smart Watch, Samsung should dedicate making Hardware not Software.

Rating: 3
I bought this 2 weeks ago with the understanding that it is a standalone device. Unfortunately, even if you purchase the LTE version you will still be tethered to your phone by the short range leash of bluetooth if you're on certain carrier networks. I've learned this the hard way. No one tells you this till you find out your watch keeps going out of range and becomes useless as a standalone device, as advertised. My carrier is Sprint and they only fessed up after I spoke with Samsung. Doesn't always track steps if your arms are not in a certain position and motion. Disconnects from WIFI and network thorough out the day.

Hard to Sync!!!!!!
Rating: 2
I bought the Gold 44m. On 12-26-19. And could not get it to sync to my Note 9. So I am returning it back to the store for another one. If this does not work Samsung you all need to try it again. It should not be this hard to sync a Samsung device to another Samsung device.

Way too buggy and was pointless to get LTE model
Rating: 1
I purchased this mainly for the sleep tracking, but I was hoping to use it for a lot more. Unfortunately, it has far too many bugs and has proven to be completely unreliable. For instance, it will miss entire nights sleep, will count time on the charger as being asleep, and oddly enough, it will correctly detect that I'm awake in the sleep tracking (for some reason, "awake" is one category of sleep that it uses), but will still count that as time "asleep", so even when it correctly (believably?) detects my sleep it still gives an inflated amount. Also, its heart tracking is horrendous! It often has me at 30-50 extra bpm when I use the tracking. The only way I've found to get it to correct itself is to change it back to manual, then do a handful of manual readings. Each reading will be roughly 10-15 bpm less until it gets down to the (hopefully) accurate value. My biggest complaint though is that I paid for the LTE version so that I could use it independently of my cell phone. This only works as intended if it's in frequent range of my cell and my cell is turned on. If my phone shuts down or restarts for any reason (low power, etc), the watch software stops it from being usable for ANYTHING other than the watch face itself. You can't even adjust the watch brightness or mute it without having to go to your phone, charge it, power it back on, and unlock your phone. So don't even think about hoping to use this in AN EMERGENCY... There have been a lot of other issues, but those are ones that make it amount to little more than an expensive fashion piece. I wish I'd gotten a different brand. Can't mention any other brands in reviews per their guidelines, but sounds like (don't) 'get this'.

This watch absolutely sucks.
Rating: 1
i got the watch to use on my workouts and record my runs more accurately but the battery dies with little to no use. i charged the device to 100% and 4 hours later its completely dead, the power save mode doesn't help much either.

BLACK SCREEN - UNRESPONSIVE- NO FIX
Rating: 1
BLACK SCREEN - After owning for two weeks, I didnt want to wear it without a protective cover, so I waited another week for it to arrive. Once it arrived I was anxious to put it to use. The watch was charged to 89% as indicated by the Wearable app on my phone. I turned it on, I could feel the haptic response when moving my finger around the bezel...no screen response. Tried all options noted by other customers. Reboot, hold power button, hold both buttons 15 seconds...nothing. Black screen. Samsung rep stated no other customers have experienced this. Not true. Even though there are responses from their technicians on their website, the tech still denied anyone else had the same issue. So...either mail back for repair and wait or return for a refund. Disappointed for sure.

Exactly what i was waiting for
Rating: 5
i owned galaxy watch and i loved it except it was little too heavy. also, i do not like fitness type watches, so i was literally waiting for watch3. super light, works well with bixby, samsung pay, and a lot of customization you can do. i always wear watch to track my sleep, and it didnt bother me at all. at last, watch trade-in was really good promotion!

Familiar but lighter
Rating: 5
i'm happy with this. it's the best upgrade from my gear s3 frontier. feels the same but lighter in weight. only drawback is the strap cause it felt a bit cheap. i got myself a silicone strap for it later on.

Perfect
Rating: 5
i got this as a replacement for the 41mm size, which was too small. the bezel on the 45mm actually seems shorter than in the 41mm! it's easy to use (both the bezel and the touch screen). the battery life is superb. the screen is beautiful. and since i had a trade in (active 2 - no bezel - good riddance), the price was great, too.

Gr8 watch, superb gizmo,fitness kit not 4 every1
Rating: 5
this is as beautiful and functional watch, phone, info pod, music player, gadget, companion and alarm as you could want, worth every cent. the learning curve is minimal if you can find your way around a smartphone. but the fitness stuff, which is touted as the centerpiece of this timepiece's acumen is just for gym rats or runners and such. i garden, walk dogs, putter around the house, dance now and then and the watch's workout detection for my everyday regimen is quite confused and almost useless. for everything else it does, and there's a lot of it and the sheer snazz of it, i love it. i'd give it a 4.7 but you can only rate in whole numbers.

Great integration with smartphone
Rating: 5
this watch seamlessly integrates with my s20 ultra and i love how i can receive notifications from all my apps on the watch. i get about 2 days worth of battery life with normal use and the always-on display turned off. best surprise so far is being able to connect to my ultra's camera and see it on my watch face and take pictures!

Great watch - so so battery life.
Rating: 4
Upgraded to the Galaxy Watch 3 from the original Galaxy Watch. Love the larger screen. Love that it's slightly slimmer. Love the new sensors, including Blood Pressure Monitoring (Not officially activated in the US yet, but there are workarounds available). Only complaint is that I'm not thrilled with the battery life. Still easily get a full days worth of use even with sleep tracking, but nowhere near the life compared to the Original Galaxy Watch which could push 3 days.

Best looking watch on the market.
Rating: 3
the design is flawless and the rotating bezel is infinitely better then the touch one on the active 2. i am used to the subpar battery life when compared to let's say a versa 2, so i don't really fault it much because the tech and os is muchhhh better then fitbit. i can't excuse away the slow charging however. it is brutally slow and for this amount of money it is inexcusable.

Just Ok
Rating: 3
i regret upgrading from the galaxy watch as there is nothing worth the expense for this watch. the extra stuff they mentioned like the workout, sleep, etc., not that great. the other watch i had was better in doing my every hour stretch reminder this one is weird, it's a hit or miss. the few things i love about this watch are the lightness and also the look on the screen. bigger and aesthetically more pleasing. battery is fine as well, get two days or so. i don't think it is worth it and when i trade in i realized i should have kept my watch.

Disappointing new design and Wear App
Rating: 1
the protruding watch buttons on the right side is poor design if you want to wear the watch for road biking and during circuit training with weights and especially push-up. my s3 is much better with recessed buttons. i am returning it until they learn to get feedback from actual athletic customers. also, what's wrong with their app design, why does it have to combine the watch and phone steps? i want to be able to just use the phone or watch, not the cumulative, which could be double sometimes or 70% to 30% and the 30% is probably already in the 70% of the number shown. makes no sense at all, separate them out. don't buy this if you are going to use if for active life, go with fitbit or some other device
