    The Runstar Scale is a fantastic for anyone serious about tracking their health/fitness metrics in detail. It goes beyond just weight; it measures and monitors a comprehensive list of 15 body composition stats, including BMI, body fat, water percentage, skeletal muscle, BMR, fat-free body weight, subcutaneous fat, heart rate, cardiac index, visceral fat, muscle mass, bone mass, protein, and body age.The display is a nice touch, making it easy to read and interpret results at a glance. Plus, the Bluetooth connectivity is seamless, allowing me to sync with the fitness app effortlessly. I can view my progress in detail, with options to track by recent days, weeks, month, or even year. A rare find on Amazon, and a truly comprehensive tool for health tracking.

    These scales are playing a very important part in my weight loss journey. I have now realised that there is more to just weight loss. It’s about BMI and fat percentage. I was eating less calories than I was expending which made me lose weight initially which brought my BMI down (which I was told by the scales) but my fat percentage wasn’t going down that much. This is because I was losing a lot of muscle mass. I am now going to the gym in order to try and maintain muscle mass which was all caused by these scales!The large screen is very useful for me as I don’t have the greatest eyesight. I have had no problems in reading the screen at all as it is nice and clear. My parents have been making use of the heart rate feature as they now know what it is. My mum is now having a bit less sugar due to it. They don’t know the last time they tested heart rate before these scales!10/10 would recommend as it is a bargain at this price

    Was looking for a replacement of my Withings scales which have died on me this time I wanted a replacement that was a better price had a good look round Amazon and decided I would try these as I want to monitor my training & health, I like the fact that these have so much information. I like the quality they look attractive, sleek & modern design they also match my bathroom. I connected to the app without any issues using Bluetooth. I wanted to change the scales to stones and wasn’t sure how to do it so I contacted Customer Service via email and received a reply with in a few hours with a video on how to do this, which was very helpful as it can be done in the app and showed on the readings on the scale and not just in the app. It gave me the confidence that if I do have ant issues they will be addressed in a timely manner. So the scales do what they say they do, the app has loads of information that I am looking forward to using in my health journey.

    My scales arrived this afternoon. Really easy to set up with the App and information linked instantly. Happy with the scales but disappointed as can’t seem to link it to Samsung Health App

    As a student who’s always on the move, I’ve found the Runstar Scales to be a steadfast ally in my fitness journey. It effortlessly connects with my fitness app, allowing me to keep up to date on various health metrics like heart rate and BMI.The scale itself is sleek and unobtrusive, fitting seamlessly into my hectic student life and chaotic student bathroom. The battery life has been quality and hasn’t yet needed a change of batteries despite a pair being included in the box which is a great nice to have! The scales have been quick and reliable and basically do what they say on the tin whilst integrating nicely with my existing ecosystem and other fitness apps.Overall, the Runstar Scales, despite being a brand I had never heard of before, are a no-fuss, dependable tool that helps me stay informed about my fitness goals. They’re an affordable option for any student and provide excellent benefits over a standard set of scales at a price that doesn’t break the bank, making them perfect for anybody who’s serious about their health, well-being and finances.
