I have been using this watch for a while, here are some of my opinions on this product, I hope it will be helpful to you.Pros: The value for money of this smartwatch is okay, and the price is not bad.It has over 130 custom digital watch faces that you can choose from at any time, which I think is a really nice feature. It can also monitor your heart rate, oxygen saturation, personal sleep status, and weather forecast information. Battery life is also okay, a bit longer than estimates from other smartwatches. In fact, there are many more functions, which are listed one by one on the product page.Cons: The watch's display is a bit small, unlike other smartwatches with large displays. But in the market, it seems that smart watches like this one, their display size is also not large. If you have vision problems, this screen may prevent you from reading, in which case you need to switch to your phone and read larger text.Besides, some of the readings weren't perfect, but I was fine with that because it was within my expectations. I haven't seen a watch with perfect data yet, including some expensive ones. Some people want it to be as accurate as a medical device, which I don't think is possible. It's just a smartwatch, not a replacement for dedicated medical equipment. Asking it to be as precise as a medical device might seem absurd to me. Of course, this is just my personal opinion.This seller is also very accommodating, I had a small issue and they sorted it out quickly.The above are some of my personal thoughts, generally speaking, this product is worth the money and can be recommended!

I am very satisfied with this watch. I would say this is one of the lightest and best watches in this price range. The application is easy to configure. Honestly, there's not much to do, just turn on Bluetooth and it will find the watch and work seamlessly. The manual is easy to understand and the features are great. I love this watch because it's small enough to fit on my wrist, has great battery life, and I can easily change the watch face of the device.This watch is an absolute game changer for anyone who wants to stay on top of their fitness goals while also staying up to date with the world around them.This smartwatch seamlessly blends style, function, and fitness tracking. It is a feature-rich device that combines advanced technology with sleek design. It offers comprehensive solutions for tech-savvy individuals.It tracks your steps, distance and calories burned and provides insightful data about your workouts. A heart rate monitor ensures you monitor your heart health throughout the day, while a sleep monitor analyzes your sleep patterns to help improve your overall health.All in all, a great watch. I'm happy to recommend you 5 stars, perfect for those who want to get information and control their smartphone without constantly taking it out of their pockets. Quality at a very reasonable cost. I can't fault it.

I purchased the Blackview R1 watch last November.The positive points are - It was comfortable to wear and easy to set up.It worked fine for 6 months and then started to malfunction, and after a few days stopped working altogether. I contacted the supplier and initially received no answer. I contacted them again and they said I could get a replacement from them, only for me to be told the next day that would not be possible as I purchased through a 3rd party, which I hadn't. I purchased directly from them via Amazon. Less than helpful communications went on with Blackview for several days without success. I have now purchased another watch, from a different manufacturer, which seems to be far superior, for the same price. If you are lucky enough to get a watch that works for much longer than 6 months then it was OK. Personally I would avoid Blackview altogether as if you do have a problem, their 'customer service team' are not at all helpful

I got this thinking the sleep tracker would be useful and the price was very reasonable. Installation of the App went ok and there is a decent selection of watch faces to pick from. The app wants to run all the time to receive data from the watch. Some will download everything since last connected but this doesn't seem to. Ended up killing the App as it was always showing in the notification area and only opening it when I wanted something. The step counter on the watch works without the app.Found the sleep tracker on the app quite unreliable. Only seemed to start at 2.00am then said not enough sleep because it missed 2-3 hours! Not sure how it senses when to start tracking sleep but it wasn't very reliable and constantly missed the start.Charge lasts well and it seems to charge pretty quickly - once every few weeks will do. If it does run out of charge, you have to put all the settings including the watch face back from the App.The loop at the end of the strap broke after about 6 months but it was ok just using the pin into the holes to close it. Unfortunately after a further couple of months, the strap broke where the pin hole is and is now unusable. Replacements were available previously on Amazon but no longer are.This is good for the price but without the strap is unusable so turns out this was a false economy for around 8 months use.
