Best watch ever!
Rating: 5
I absolutely love this watch! Bright and vibrant, connection to my phone is amazing! I highly recommend! I got the 44 for reference, go big or go home!

Satisfied customer!
Rating: 5
7th day wearing this watch and have charged it one time from initial full charge (at 42% now). Thought I wouldn't like it because it doesn't have the rotating bezel, but I am getting used to it. The band fit very comfortable unlike my Gear band, I had to order a more comfortable fitting band for the Gear.

Excellent Pebble Replacement!
Rating: 5
until the galaxy watch active 2 came out, there was not a worthwhile contender for my pebble imo. this watch meets all my requirements and even has a touchscreen! i can talk to it, listen to it (couldn't do that with the pebble), control music with it, and do all of the other things i need with it (appointments, texts, phone calls, etc.). i even found a text based watchface (one of my favorites for my pebble). i am very pleased with it so far, and even the battery life has surprised me (i avg. 5 days/chrg, but i don't use any of the fitness/health tracking stuff and i turn off wifi and bluetooth every night). i'd have preferred a stainless steel band instead of the rubber (so i picked one up). i even find bixby quite useful/helpful. nice watch and looks to be an awesome replacement!

Amazing Watch!
Rating: 5
i had done some research in finding an affordable, reliant, and durable watch. the samsung galaxy watch active 2 met all of the criteria! once i purchased the item, it was very easy to set up and get going. you can change everything in your watch from your phone, using galaxy wearable, which i find is very handy. i would recommend this highly to anyone looking for a smart watch with the same criteria as myself. one thing i noticed, however, is that in ordering on samsung.com, it was very confusing because they made you buy the watch, band, and charger separately. i ordered it through samsung on amazon, and it came with everything for a much lower price.

ALEXA on your Galaxcy Active 2 ?? YES you Can!!
Rating: 5
This new Galaxy Active 2 watch does it all!! I’m not a fitness fanatic, so I will not comment on the accuracy of the calorie count or heart rate monitor. I'm happy to know my daily steps taken, be reminded to move when I've been sitting too long at my computer, know my ticker is still tick’n, and receive kudos when I've reached my daily goal. First of all this is a stunning piece of technology, very sleek, and looks great on any wrist. I replaced the pale pink silicone band with a slim black leather one so it looks very sharp and professional. The Pink Gold color keeps the watch looking slim, not bulky (although the Aqua Black was intriguing), and blends well with most skin tones. I chose the 44mm for better battery life - yes, I get 3 days between charges. I also like the larger screen for easier interaction with the touch screen, which by the way is very clear, bright and easy to see even in sunlight! LOVE LOVE LOVE, that I can receive and respond to texts and calls. I have found that the 30 foot maximum distance to my phone requirement is actually conservative, my phone has been further away from me than that and I still receive texts and calls. I work in a showroom where I cannot have my phone with me; I can now react immediately when I'm contacted. For texting, I can use voice to text and even edit my response after I have spoken it using my voice again or hand writing on the screen. There are endless emojis I can reply with and I can send and receive texted images. I can ANSWER THE WATCH, if my phone rings. There is a mic and a speaker on the Active 2, and the voice clarity is perfect. I can also reject a call right from my watch and send a text back instead, like letting the caller know that I'll call them back in a bit. The Galaxy Active 2 also gives you detailed quality of sleep feedback. It does a great job breaking down time spent in REM vs the other sleep phases. And with the ability to fully charge in about 2 hours, every 3 days, you can absolutely wear the watch to bed every night to benefit from that useful information. The watch is completely customize-able. You can choose what notifications you want to receive on your watch and how (vibration, sound, or both). With the Do Not Disturb feature, you can also schedule hours at night that you won’t receive any notifications at all. You can arrange the widgets in any order, add and subtract Apps, and navigate by scrolling between them or use the digital haptic bezel. The digital bezel adds a bit of class to the watch and works flawlessly. It's responsive and brings back that rotating functionality that the first Galaxy Active lacked. I have uninstalled the Apps I did not find useful to conserve battery life and added a couple, including Alexa. YES, ALEXA!! I added the Alexa App, called "Talk to Alexa" In the companion "Galaxy Wearable" App. You can find it in the App section: Discover>Top Watch Apps>Categories>Lifestyle>Top Paid. I can ask Alexa to answer questions, things that I would typically Google on my phone, in addition to finding out the weather, set timers, and control my smart home, RIGHT FROM MY WRIST! I have tested various requests using my Active 2 vs asking Alexa in my home. The responses were identical. The first photo below is of Alexa ready to listen, and you can program her to launch when you double tap the Home button. This is an amazing Smart Watch, get it, you won't be sorry. Now complete with Alexa, this is a perfect alternative to an Apple Smart Watch if you are an Android/Samsung phone user... I have been using it since the day of its release and it is a fun watch to use and a wonderful companion. Click below if you found my review helpful. I purchased this watch at full price and was not compensated for my review…

It's a excellent product
Rating: 5
This is an excellent product for me. I can't speak for anyone else, but it's the right size display, looks good, if fact I have kept the orginal band. Except for the "Iwatch" I've tried alot of smartwatches and trackers. Active 2 has the ability to track fitness, provides very good smartwatch features and looks great. Highly recommend.

It does most of what I needed.
Rating: 4
It was probably a 3 star watch before I figured out I could buy new faces for it solely because I didn't like the look. I was worried about the 44 being huge since I have small hands but went for it for the battery life. I'm not disappointed. It isn't overbearing and it's very lightweight. I had to restart it one day because it stopped doing anything but it came back on and other than that I haven't had any issues. I mainly use it to control my music and for alarms. I like the phone function when I'm in the car also. I would like messenger to work better with it because I don't real text many people. I haven't figured out how to send a message really on messenger, just reply. I haven't looked it up either though but it's not an available app on here.

Great Smartwatch
Rating: 4
I've had the watch for two weeks now and love it. It takes some time to get to know how to use. My advice is to turn off the voice assistant ASAP, it's annoying. My only complaint is how it records the floors climbed. I've been on the Samsung site and tried all their fixes and nothing seems to make it work better. I've used Fitbits for years and they work great. Not sure why Samsung can't figure it out. I would familiarize yourself with the features on Youtube to make it easier when your watch arrives.

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
