Just get it
When I first saw the price I was greatly concerned that there were a lot of corners cut to reach that price. However what they did was cut a lot of fat that for the most part basically seemed unnecessary. The screen is great and I leave it on adaptive brightness since it reacts to the ambient light well. It gets bright enough in the day and dark enough in the night, pretty easy to tell what time it is or what your notifications are. The wrist band is honestly the only big complaint I have. Not exactly meant for big wrists, I'm 6ft but my wrists are somewhat small, for most watches I'm usually on the last 1/3rd of the strap. But for this band I'm on the second to last notch in the belt, so it seems like this is meant more for kids, teens and adults with super thin appendages. However there are many alternative wrist bands available on amazon so you could easily buy replacements. No wifi and onboard GPS made me worried, but I remembered back to my older Samsung watches and I usually turned them off to conserve battery. Of course that might have some concerned but as long as you have the GPS on with your phone you will be just fine. The software is somewhat limited too, but looking on the watch or the Wear app on your phone lets you more easily customize everything and give you a better idea of what you can do. I made sure to reorganize the widgets and settings as well as customizing which quick actions can be performed on the small screen. Sure, I miss the tactility I had with the clicky bezel of my first Gear Sport and I really wish I had a battery efficient version of a Samsung watch with that tactile circle, but honestly the touch screen will do just fine, even though it makes the thing look painfully generic. Battery is amazing. Even though this thing is billed as a fitness tracker it still does basic smart watch things all while not needing to be recharged every 18 hours, in actuality this thing lasts me the whole week! I really wonder exactly how Samsung got the 13 day battery life metric, I think you would need to heavily restrict a lot of the stuff the Fit 3 just to achieve that. But that doesn't stop me from appreciating the nearly week long battery, and charging it up is super quick even with a low watt charger. I got a 15 watt usb-c brick and it's easy for this thing to reach 100% in under an hour and some people even say you can just plug it into your phone and charge from there. All in all, if you ever hesitated to buy a smart watch because of the price, the battery life or just the usability, give this a try! Sure there are limitations in the software and hardware, but it's $60! Even if it's a mediocre fitness tracker and smart watch, it's less than 1/3 the price of cheap mainstream smart watches that barely hold 2-3 days of battery!

This Galaxy fit 3 is really nice. It is light and not too bulky on my wrist. It replaced a Galaxy fit 2 that I have used for over 4 years. It hooked up to my phone as I was taking it out of the box. It was ready to use in about 10 minutes. I am still learning how to use all the new features that it has. I walk over 10,000 steps per day and the GPS keeps really good track of all my steps and speed.
