I've had this for just under a week now and so far I really like it. My only legit complaint is the knobs and buttons on the side of the watch frame. I wish they were flat, I find that I accidentally long press the google assistant button a lot when I have to bend my wrist for more than a second. This hasn't been enough for me to return the watch though. I've just ended up pushing it up on my wrist a little higher and it seems to have helped. Additionally, the wrist straps are incredibly easy to swap. There's just a little silver nub where the band connects to the watch on the underside, you have to slide and hold it and the band comes out. Makes for incredibly easy changing between sport bands and nicer leather or metal bands for more formal situations. I took them both off and put them back on in less than a minute.Now for the big stuff -- I'll get right to it first and foremost since it is mentioned in a lot of reviews. The battery...**For anyone claiming to have terrible battery right out of the box, I suggest installing all the updates and doing a full overnight charge first. Battery performance was a little wonky during setup and while downloading and installing the updates, but after the first night it's been great. If you still have trouble then I suggest returning it or contacting Fossil for support for defective battery. ***BATTERY LIFE - I've customized some of the features, but for the most part they're all on. I've only turned off the sound and the ability to answer and take calls on the watch. I've never had to do take a call on my watch and I just see it as an irrelevant feature personally. Additionally, I don't have the screen set to "always on" or "touch to wake" and instead use "tilt to wake". I start my day at 6:30a with 100% watch battery and arrive home about 5p every day and haven't fallen below 60% battery. This is with the features below on and with normal use by replying to texts, tracking walks with GPS, setting timers and alerts and occasionally using the google assistant.I have the following all turned on 100% of the time:-GPS (only activates while tracking exercise)-Wifi - always on and connected to my phone when not in bluetooth range-Cloud backup-Heart rate monitoring (set to measure HR every 10 minutes all day)-Google Fit SyncingWater resistance - According to the Fossil website, this watch is 3 ATM rated water resistance which means you can shower, wash your hands, get sweaty, etc without worrying. The 3 ATM rating means you should (in theory) be able to submerge your watch in water while swimming up to a depth of 100 feet. I personally don't know if I want to test this, but I have gotten it wet while washing my hands and its been fine.It's got a little bit of weight to it, so coming from a samsung gearfit that was rectangle and very light, it's taken some getting used to with the weight and round shape. It is a solid watch though.The screen is excellent, I've used it in a variety of lighting, including high-noon direct sunlight and the screen brightens up and it's perfectly readable. If you have bigger fingers, some of the buttons can be a little annoying to tap, but overall I've not had any major issue with the touch screen.The silicon strap is comfortable and has many notches for the perfect fit. As I said above, also incredibly easy to swap between the sport bands and a nicer leather or metal band.In conclusion, I was worried a little bit about getting a round watch and I had been keeping my eye out for a square option, but I haven't found any with Wear OS support (this was important to me for fitness tracking with google Fit). I'm glad I went with this option though because the watch looks great and I can get a nicer band to wear to more formal functions.
