I am very happy with this scale! It’s super easy to use and gives quick, accurate results every time. The display is clear and easy to read, and I love how sleek and modern it looks. It’s lightweight, but also sturdy and doesn’t feel cheap at all. I really like that it turns on instantly when you step on it, and it turns off automatically to save battery. It helps me keep track of my weight in a simple and reliable way. If you’re looking for a good quality scale that looks nice and works perfectly, this one is definitely worth 5 stars!

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.

This smart scale has completely changed the way I track my health goals! It connects to my phone via Bluetooth (or Wi-Fi), and the setup was super easy. The companion app syncs instantly and gives detailed breakdowns like weight, BMI, body fat percentage, muscle mass, and more — way beyond what a basic scale offers. I really like being able to see trends over time and not just one number. It helps me stay motivated and adjust my habits when needed. The scale itself looks modern and sleek, and the glass surface is easy to clean. It's also surprisingly accurate and consistent with each reading. If you’re looking for a smart way to stay on top of your fitness or health journey, this scale is 100% worth it!
