    • PERFECT!
Review Image by TristanM TristanM
This watch is everything it's cracked up to be! Samsung 4 watches are usually $100+ BUT NO this one is $50?!? The product arrived EARLY!?! It was super easy to set up exact or better condition then what was stated. There was no clickbate, no lies, and it's not a scam. It 100% paired with my phone and said it was a Galaxy Watch 4. It's size is perfect for everyone! It's very comfortable as well. It monitored my sleep practicly on point. It's also very good with Bixby, Messages and other features as well! ... show more

    • Great budget smart watch!
There are two things I don't like about this watch. First, it comes with the standard Samsung band and charger which are not very impressive. I bought some 3rd party accessories that look and feel much better. Second, the battery life. I have had it for 2 weeks, but I feel like the battery drains faster than it should. I read online that the watch is suppose to learn which features I use and improve with time. Otherwise, this is a great watch for the price. ... show more

No lo recomiendo en lo absoluto, entiendo el concepto de producto renewed, pero que se te vea comprometida la pantalla con golpes y este deformada, compromete el funcionamiento del tactil, lo cual no garantiza que el rpoducto te vaya a durar mucho tiempo funcional

    • See to work as well as the Fitbit I had that died for sleep tracking and pulse. BUT ...
The ban that comes with it is garbage, but I bought one of the expandable nylon (?) bands. That works WELL to hold it on write firmly - which is necessary for all the health functions. Sleep tracking works at least as well as my HR2 - and I believe somewhat better. I am using the Oxygen sensing while sleeping as well as heart rate. The ECG will ONLY detect AFib as a diagnosis - but you can look at the trace - especially on phone app and get a good idea. It would be better it is was lead II rather than lead one. For example, with lead one you are not really seeing atrial flutter at all. With lead 2 you can. But to do that they would have to go between left leg and right hand. I do that with a handheld ECG - and that allows me to see much more. Overall seems well designed - and my only beef is the vibration. The Fitbit HR2 would reliably wake me with the vibration mode - which did not disturb my wife. Not so with the S4 Watch. I can barely feel the vibration with I am awake and just sitting at my desk. The need a MUCH stronger vibrator. IF you turn off the functions you do not need - and you do not use always-on display - you can easily get more than a days out of the battery. Leave everything on as it comes from the factory - and you will be lucky to get a half day. Look for an article on internet of "what to do to optimize battery life, etc" on the S4 Watch. ... show more

First off, the seller I got this from was great. Arrived on time. Watch didn't have a single scuff or smudge on it. Literally like new. Box is generic, but everything inside looks original including the charger and the manuals. The battery was a little low (56%) when I got it, so I gave it a charge before set up and it was full in no time. Watch itself is great. Easy set up as long as you follow the directions and use the app. Picked a simple watch face and called it good. The main complaint I saw about this watch is the battery life. I read up before getting it and adjusted settings right off the bat. I don't keep the face on all the time (1. For battery life and 2. Some users had screen burn) I don't care much for the health things, so I have all preferences like the bpm monitor set to manual so I use them as I see fit instead of them either going continuously or every 10 minutes. If you have bad eyesight like me, use the large font setting And for the love of everything, download the Gboard app. Like literally right out of the box past set up, get it. Otherwise you have to use T9 and text like it's 2000 again. The only downside (for me) is I have tiny wrists and the standard band is way too large. There are large gaps on either side. This isn't really a downside, I just had to spend a little extra on a new band. No biggie. Over all, great watch. I may just get my partner one too. (It now has a walkie-talkie app!) ... show more
