SamsungGalaxy Watch 4 Bluetooth & GPS Smartwatch, 40mm - Black

Ya llevo bastante tiempo con el y la verdad excelente y sin ningun inconveniente.

Uodate**I have worn this watch now for a while and while I love it, it gets hot. And when it takes my heart rate, it burns.. I don't have sensitive skin and I have had no problems from other types of watches, apple and fitbit.I have always love samsung over all other options! I have been an avid samsung user for almost as long as they have been a thing. I messed up and switched a year ago to a competitor and hated it. But didn't want to spend the money on a new phone and watch so quickly. Well, I finally had enough and ordered a new samsung phone and watch. This watch is amazing! The battery lasts as long as I need it to, I charge it nightly anyway. I have not gotten any burns on my wrists but I don't have sensitive skin. Once the watch was all updated, the battery did last longer. The updates will drain it fast! Glad I took the plung! My watch did have one error that I had to figure a work around for, I'm in the US and when setting up the watch initially, once I choose English (united states) then it wanted to know country location. The US was not one of the options. So I randomly chose one, this hasn't hindered the watch functions!

I started with the original Samsung Galaxy smartwatch when they were still using their own OS and was very happy with its usefulness but almost as frustrated with the lack of Android friendly development on the apps side. Stepped away from that to a specifically Wear OS based watch, but unimpressed with the battery life. Skip ahead to this year and instead of jumping all the way up to the Galaxy 6 I decided that the 4 looked more than a fit for my needs. I am so glad I did. Not only was it far less expensive, but it does exactly what I was hoping it would. Bonus: the battery life is phenomenal!

This is an international version (Central and South America and the Caribbean) that does not function in the US. When you set it up it does not have USA as a region selection. That determines a Country Specific Code (CSC) built into the software and that code changes the functionality of the watch. You will likely be unable to download and use US apps (G Pay for example is not available in most countries, and thus this watch is not able to use it). It can even restrict the use of certain hardware in the watch based on government requirements in those other countries. The seller is aware of this because after digging into the reviews I see others have noted the same issue, yet the seller still does not disclose that this version is not functional in all countries. For some reason Amazon has allowed this to continue. I am returning it and will look elsewhere for a US model.

Battery life is not okay， everything else works fine

This is a replacement for one that I damaged. It is slim and trim, more classy looking, and it does everything the bulky, oversized ones do...finding the watch when I misplace it is easy with the app. I am glad to have one again!

I've used Fitbit for years, but with the changes to app and everything, I had decided to make a switch. I am so happy I did. Since I went for the 4 instead of the 5 I got a great deal on the price. Also, this is such a cool watch. So many features and I don't have to pay for the health data that I was paying for with Fitbit.

Exactly what I was expecting right out of the box. It needed a charge, but charged quickly (about 90 minutes to full). Needed several updates which means Samsung supports their product. Updates and app downloads quickly drained the battery, but once all that was done, the battery lasts all day and quickly charges in under 2 hours. I use it for messages, phone, scheduling, my fitness pal, Samsung health, and alerts from my Dexcom app (can't get the g watch app to work between my phone and watch just yet to be able to read my current glucose level).
