Loaded with features but unable to do simple
I bought this a month ago because I was tired of charging my apple watch. It's been great for that as a smart watch. My main complaints are: 1) The battery life/display bug that was not fixed with the latest update (which I had to get connected and Express to enable!); and 2) That it does not have a silent, vibrating alarm to wake up in the morning (or if it does, it doesn't work).

Nice watch and GPS
Works great, tracking distances and have it paired with GPS Dog collars, super easy to watch and keep track of dogs and points in big fields with tall cover!

Instinct 3 / 50mm / Solar
Had the original Instinct and could not have been happier with them. Up graded to the Instinct 3 and they did not disappoint. Went with the 50mm face for easier reading and the solar version for longer battery life.

Watch
I bought this a couple weeks ago and it’s a good watch, however the battery doesn’t last as long as I thought.

Very poor solar capability.
Own an old Casio that is still only being charged via solar after 25 years. This watch have very limited solar capability and need to be charged via cable so useless on a long adventure. Returned

Instinct 2 now an instinct 3
I had an instinct two that still works and was absolutely bulletproof for 5 years. My instinct 2 went through junkyarding wrenching on cars being dropped all kinds of stuff and the thing was great. I have a feeling that this instinct 3 will be of the same quality. Garmin genuinely builds a quality product. Very pleased. I decided to purchase the instinct 3 solar due to the ability to monitor my blood glucose with apps available on the store. So far very impressed with the watch build quality is good. The flashlight's kind of cool helps at night and solid product.

Game Changer
This watch not only does what watches are supposed to do, but it educated and motivates as well. I have probably learned more about my physical health while learning how to navigate and operate my new Garmin Instinct 3 than any other time in my life. I like being able to see the numbers and then be able to see what they mean, how they are calculated, and why they matter. Couple the information with workout plans, coaching plans, and connections and you have a one stop shop for better health and motivation. Don't think I will ever own another brand watch.

Garmin 3
After my Garmin watch stopped working, I went back to my old Samsung watch. I finally decided to get another Garmin. You never know what you use until it isn't there to use anymore. Really like my Garmin watch.

Great watch
I got this watch a bout 3 weeks ago after seeing it on an online ad. I hadn't heard of the Instinct 3 so I looked it up. Saw that it was a 50mm and bought it. I have 2 Epix Pros, Fenix 6 and 7 and the Venu X1. I like watches. The Instinct 3 is by far my favorite. I don't use it for it for what it's intended for. I just got it and like it because it's a big watch.
