    • Good but large smart watch

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

    • Love, Love, Love
I was worried about it being refurbished. I've had bad luck before. This watch has exceeded my expectations. Battery life is short-ish. I get about 3 days on a charge, but I use it endlessly. Constant heart monitoring, messages, music, all of it. I cannot complain at all. This is my 3rd Galaxy watch and by far is my favorite. I've had it for 2 months now and I am always finding new things it can do. Love love love! ... show more

My samsung watch looks and works good. The band looks and feels new, very comfortable. I think it may have had some grime left in the corners of the screen edge. But otherwise looks new. No blemishes or scratches. 40mm. Has great features like sleep tracking and heart rate and activity monitoring. I charge mine for under 30 minutes in the morning and the evening. Battery life seems to depleate quickly. Amazing watch for the price. (Refurbished) ... show more

    • Battery in the watches are bad, not worth the money.
I ordered one for my son and it wouldn't last a complete day. I figured he had all the bells a whistles on and suggests he factory reset it. No luck so we returned for a replacement. This one has about the same issue, it will get through the day with all the eco settings on. I have a store bought watch 4 so we compared settings. Same result. I contacted seller for help and I'm getting the feeling they are not going to reply. The watches are as bad as everyone else says they are. ... show more
