  1. It Works

    What I like. Very comfortable to wear. Sensitive touch screen Easy to use. Heart rate monitor seems very precise compared to other heart rate monitors I have. Cool features I have not seen on other fitness trackers.I do wish it had more style as it is a very simple design.
  2. You don't often get this much style and value for so little money.

    I've had this watch for a week now and it's a great looking watch that was set to my computer clock and is still within 10 seconds. I use it as a dress watch and it fulfills that role to a tee. Very light weight and comfortable. The date can be a little hard to read. This is not a small watch but it's nice and thin which for me is a big plus. Nice watch that I will enjoy using.
  3. Update on review

    I reluctantly wrote this review driven by what appear to be some (minor) design flaws. Unfortunately the flaws were in the one feature that drove MY buying decision. If you need a good watch/fitness tracker I would recommend this - if however the feature you are seeking is SpO2w accuracy you might hold off or seek another solution I am satisfied with the other functions that are provided.What drove me to edit this review was to cite the great follow-up service I received - specifically fro 'Cris' (sorry - didn't get a surname). He doggedly pursued this in MY interest until we had a satisfactory result. Kudos go to Cris and the service/support team.Dave TylerOverall nice design, decent battery life and basic functions were fine. I purchased this as it was the only one I could find on the web that incorporated an SpO2 (oxygen saturation) measurement. That was the MAIN reason to select this product as I have respiratory issues and loved the idea of having the feature on the watch thus negating the need to ake and Oximeter everywhere. I gave it a ten day trial to verify the SpO2 readings against my Oximeter as well as the ones at the respiratory clinic I go to. The reading were not even in the ballpark (off by as much as 10-15%). Noting this I then did the same testing for blood pressure (versus clinic equipment) and the readings were as bad or worse. I contacted their customer Service (email contacts only as the are on Mainland China time and I live in California) so every email exchange loses 1-1/2 days floating thru various clouds. While the service people were responsive the communications were painful at best.They did agree to send me their "latest improved version" and I got it last week. My findings were:1) It is the EXACT SAME watch as the first one. Same everything - product, packaging and useless user manual.2) It appears to be used - watch face scratched up fairly noticeably.3) Same erratic performance.I'd avoid this company and be skeptical of any other products they have on Amazon.Dave Tyler
  4. Great smart watch

    I love this watch, it looks good as well. So far everything works fine. I get messages and call in this watch, its useful for me because i cant use my phone at work so when i get urgent messages or call ill know it. The heart rate, BP monitor and pulse ox is great feature, and all the values are accurate. I usually recharge the battery every other night and charging is super easy as well.
  5. Good value for money.

    Stylish & elegant. Large size display and comfortable to wear. Tracks all the steps & heart rate making it suitable for gym. This also has an additional feature of notifying about the messages & click pictures.
  6. Helpful and convenient

    This watch is helpful and convenient. I wear thid 24 hr and this i love so much more. It's conveniently on your wrist and out of the way. Tracks my activity through the day so I can monitor not only my heart but the times of the day that I tend to have the most activityI have tried this product for 10 days, I bought it because I lost one that I had. and unlike the previous one, it is much more secure to the strap, avoiding falling with a simple blow. the connection to the cell phone was very simple and fast. I give it 5 stars for being much better than the previous one.
  7. No entiendo dónde enviaron mi rembolso

    Nunca recibí mi rembolso
  8. I like it.

    For the money I think that this smart watch is a great buy. The battery does not last as long as I have read however, it will go for 4-5 days on a charge. Overall I am very satisfied with my purchase.
  9. No muy satisfecho

    De mucha utilidad las características inteligentes aunque hubiera querido que hubiera una que funcionara con cinta caminadora , cuando se usa la función de BPM cuesta regresar a las otras funciones hasta que uno lo apagaLa vida de la batería muy mala ya que apenas el día tiene de duraciónLa pantalla táctil regular ya que a veces muy difícil de que reaccione
  10. I will recommend

    I love this watch is easy to use and good quality.
