This watch is pretty great. I bought it was a renewed watch since I wasn't sure how much I'd like having a smart watch, but I'm pretty happy with it. It's my first smart watch; I bought it originally to keep track of my steps/general fitness and for the obvious time function itself. For the most part, I haven't had issues with it. I've dropped it a couple of times, I've dropped something onto it and smacked it into something when swinging my arm around, but there's no obvious damage to it at all, it still functions as intended. The wristband is also holding up surprisingly well, given that I've had it for over a year from when I originally bought the watch (ordered it 5 Feb 24). My ONLY real grievance about this watch is, because I wear it on my left wrist, when I bend my hand back enough it'll trigger the buttons. During exercise, this'll pause my workout tracker; outside of exercise, it can trigger one of the trackers to start tracking something I'm not actually doing. Both are annoying, but they're minor inconveniences. Otherwise, it does what I want it to: tracks my steps, fits correctly, tracks my workouts, tells me the time. The "AI" function on it, Bixli, is kind of useless? I don't know. You have to yell at her to make her listen, and even that's a struggle. I've tried her out a couple of times and it didn't go well, so I just disabled the function. The other features are good though, and there's apps you can download if you want to really personalize your watch face. Otherwise, Samsung does have a lot of good ones to choose from in the watch itself. Oh, I've also taken this watch swimming and into the shower and it did just fine. The water might trigger a sensor to where it thinks you're trying to do something on the watch if it hits it just right, but otherwise no issues. It also has a water "remover" function that you can scroll to and it'll vibrate to shake the water out. The battery life is pretty good. I usually charge it every night or every other night, especially if I know I'm going to the gym, but general use it goes around 2-3 full days before it needs another charge. Obviously, the more you use it, the sooner it'll need to be recharged. You can just slap it onto the charger base and you're good, it doesn't take long to recharge at all. For example: right now, my watch is on standard power mode and says 88% battery left. It estimates it has 2 days, 5 hours, and 21 minutes of battery life left. It was fully charged this morning, before I put it on and went to the gym. The text function is also good, you can read texts pretty quickly and it has quick responses for you to send, or you can write something out on your watch face, but that obviously is a little more time consuming. Phone calls also go through and you can answer them on your watch, so that can be a handy function as well, but I rarely use it. It obviously has other functions/apps you can add to it, but I'm just telling you what I use and what works for me. Overall, I'm happy with this watch. I recommend it if you just want something simple for time and tracking things.

Great watch. I needed something for my husband that would be easy for him to use and navigate through the functions and this watch is perfect. It tracks steps, heart rates, has calendar, messaging and answering capabilities plus its waterproof and durable. The multitude of functions are easily accessed too. Just overall its great and comfortabletowear since its not bulky either!

Watch itself is great, looks very nice, screen is great, functionality is good, especially for workout tracking. I use mine mostly for phone notifications, workout, health, and sleep tracking, checking the weather, and controlling music. Does all these very well and looks good doing it. Battery life is over 2 days, even when I've tracked workouts both days, which is a big step above my Galaxy Watch 1, which I would have to charge almost daily. And for the price (about 100$ right now compared to 300$+ for the newest generation) it's way worth it. I was a little worried about the size, but the 45mm Galaxy Watch 3 is just a bit bigger than the 41mm Galaxy Watch 1, so they were definitely more efficient with space this time around, fitting a much bigger screen on a slightly bigger watch. Unless you have very very thin arms, you'll probably be happy with the size. The only bad thing is that mine came with two noticeable scratches on the glass face, and a couple on the bezel. I thought about returning it but didn't want to go through the hassle, since the glass scratch (the one I cared about most) wasn't really taking away from my experience. It's mostly noticeable when the screen is off, but when the screen is on it becomes a lot harder to see. Also I'm not a huge fan of the leather band it came with, but it does the job well enough, and you can find plenty of replacements on amazon.

I was so excite when I ordered this watch. first it came with no instruction paper, so I had {you tube} how to install it, it took a long time for me to figure it, out but I did. the charging just a day and half only, witch other watches that I use to have, stay charge was a lot longer than that. it looks like is very accurate on steps and sleeping too. I love the feel of the watch it's nice and heavy not plastic just like some others, and looks very classic watch, that's what I love about it. I just give it 3 stars because it doesn't hold the charge longer.
