Best Scale Ever!!
I’ve been using this smart scale for a while now, and I really like it! It’s super easy to use and gives me more than just my weight — it also tracks body fat, muscle mass, and water percentage. I love how it syncs straight to my phone so I can see my progress over time.The design is sleek, the numbers are easy to read, and it keeps me motivated to stay on track with my wellness goals. The only thing is the extra numbers (like body fat %) can vary a bit, but overall it’s a great scale for everyday use!

Maybe good.
Idk. I had higher hopes, but this is the first body fat measuring i’ve owned. It says, I have twenty two point nine percent body fat. But I don’t think this is accurate, I think it’s much lower. When I look in a mirror I have clearly visible abs, which, in general, only happens when someone’s below ten to twelve percent body fat. I was a certified personal trainer, and I spent twenty years on fitness.I know wha t he ll i’m talking about on this. It measures body fat through bioelectrical impedance, which is like those handheld things you can use at some gyms. I used to use them with my clients. They tend to overestimate the body fat you have when you’re on a very lower end of it, and underestimate when you’re on a very higher end. They’re cheap and not the best accuracy but plenty useful for most people most of the time. The scale does measure to the tenth of a pound and matches my other skill that does that. That part looks reliable.As for the durability, their app want you to register the product. When I scan the barcode, it brings me to a website that does not list this particular model. Customer services in hong kong. There is no phone number and it made me download WhatsApp. Which there is currently no response. I guess I’ll make this four stars instead of five. But for $35 or whatever i can’t imagine the other scales are much better. Now if you’re gonna go and spend two hundred on a similar scale, it probably is a lot better.

Me gusta mucho esta báscula por todas las funciones que incorpora. No solo te dice el peso, sino también el porcentaje de grasa, el IMC y hasta la frecuencia cardíaca, todo con bastante precisión. La pantalla es grande y se ve genial incluso con poca luz. Lo mejor es que se conecta a una app donde puedes llevar un seguimiento de tus progresos y ver gráficas súper útiles. Además, es muy resistente y aguanta hasta 180 Kilos, así que sirve para todo tipo de personas. Me gusta que mide como 15 métricas diferentes, lo cual motiva bastante si estás intentando mejorar tu forma física o simplemente cuidarte.

Je suis vraiment conquis par cette balance ! Elle allie élégance et légèreté, avec un grand écran très facile à lire. La connexion à l’application se fait en un instant, et les données fournies sont très détaillées : poids, IMC, masse graisseuse, fréquence cardiaque, et bien plus encore. C’est extrêmement motivant de pouvoir suivre ses progrès directement sur son smartphone au fil du temps.L’application est intuitive, les graphiques sont clairs, et la synchronisation s’effectue automatiquement après chaque pesée. De plus, son design noir brillant s’harmonise parfaitement avec la salle de bain.Je la recommande sans hésitation à tous ceux qui souhaitent surveiller leur santé de façon moderne et fiable.
