ABSOLUTE PIECE OF TRASH!!!!
I wrote a product review before and I don’t know what became if it. Absolute rubbish and waste of money. First the item came all scratched like something that was used for an eztenses period of time!!! The seller did send a return slip but it wasn’t worth my while to return as this item was sent to my box to be shipped overseas. Then I decided ok…may as well try to salvage some usage out of it…overheating, poor charging and a host of other issues with this obviously used and obsolete piece of trash. A real rip off if you ask me. This is the screen now after less than 2 weeks of usage. RIP OFF

Blood pressure doesn’t monitor
I purchased strictly for blood pressure and heart rate monitoring. Does not monitor blood pressure. You still have to use a cuff and it helps log and keep track. Gave it away and purchased a better smart watch

Worth it!
Great watch for the price. Great condition and no scratches on the face. After updating the software everything ran very smoothly. The battery lasts about 36-48 hours depending on usage but that is perfect for me. It charges fast and does everything I need it to do and then some! It had no problem connecting to my new Galaxy S25+

Samsung Galaxy 4 watch
Works great. Excellent condition.
Kyle B. –
Not as (excellent condition) as you’d expect. But not bad either.
Aside from a bit of wear and tear showing around the edge of the watch face (screen is 100% untouched. Watch came basically dead and needed about 15 minutes of updates. The watch is of the quality that the post describes it to be. Expect it a to come lightly used but not in bad shape. My 3 stars are for the watch not being as clean and brand new looking as (excellent condition) would lead you to believe. Functionality however, is the quality ude expect from a Samsung product. Over all for the price. Not a bad buy. I’d suggest a new band and maybe a watch face protector to go with it.

Es una pasada este reloj!! Si bien la baterÃa no dura mucho como una Smart band con cargarlo mientras te bañas es más que suficiente, me llegó impecable el reloj y después de meses de uso no he tenido problemas, estoy muy contenta con mi compra
Erick Diaz –
El reloj en si me gustó mucho, es muy ligero con una muy buena Pantalla, viene con wear OS y se actualiza apenas lo sacas de la caja. Lo único cómo en todos los smartwatch de este tipo es la bateria, apenas le sacarás dÃa y medio como mucho de ahà en fuera es de lo mejor del mercado. Para mi mala suerte no es compatible con mi celular ( un realme gt) por eso tuve q devolverlo, no tuve problema con eso! Amazon muy bien en ese aspecto
Fernando –
El reloj esta como nuevo… son de excelente calidad… a excepcion de la bateria que dura 1 dia y medio o tal ves menos.. pero eso ya es de fabrica asà son todos
Rodrigo –
Para el precio que tiene llego en perfectas condiciones fiscamente el problema es la poca duracion de bateria, quizás para medio dÃa
Luis Damian –
Me llegó en un buen estado el reloj pero su carga es lenta lleva 1 y 30 minutos cargando y apenas cargo el 35% , lo recomiendo
