Me encanto, llego a tiempo , fácil de instalar en tu teléfono y usar !!Well, I bought this smart scale because I used to be certified personal trainer and aerobics instructor but it’s been a couple years since I’ve trained anyone, or even got into my own training for that matter, just little stuff every so often.. But lately I’ve been trying to pull myself back up, and bringing myself back to the way I used to be when I was a trainer is a main goal for myself right now, as well as the fact that I’ve actually convinced my girlfriend to train and everything with me so we can both get into shape, hence the need for the smart scale so I can keep a close eye on as much metrics and measurements about my body as I can because I already require more calories then the average person just to keep weight and not lose weight, so putting on weight can be hard and this scale was purchased to help me get a better grasp on doing stuff like that and all I gotta say after this short introduction into my life long issues with my weight and energy levels, is that this smart scale has done more then meet my goals of getting a better grasp on my weight, and has made my girlfriend and I really happy that I’m able to actually monitor what’s going on at that moment with my body as well as makes it a cake walk for me to just go through the 23 different metrics and measurements the scale gives me, which makes it even easier to figure out in minutes what i gotta do and what kind of routines I wanna work with!! This scale is honestly just amazing to me, and I definitely recommend this scale to anyone that needs a more precise scale and more info on themselves then just the overall weight of their entire body put together!It took me a few days to get the app connected to the scale, but this could have been a problem with my Wi-fi router, not the scale's fault. After rebooting my router, I was able to connect no problem. I like that you can set up different profiles, so I can share the scale without compromising my weight tracking information. The LED display is bright and easy to read. The displayed weight shows once, blinks once, then there is this little animation and the weight appears one last time. This is great for people with poor eyesight (or if you forgot your glasses) because you can step off the scale and bend over to read the display before the displayed weight disappears.What I do not like: You step on the scale to turn it on. About 1 out of every 3 times, it records a very small weight, like 2.4 lbs, instead of going back to 0 when I step off. Maybe I am just too slow. Anyways, when this happens, I have to go into the app and delete the wrong weight measurement.I am not impressed by all the other health tracking information, as it seems to be estimated just on my weight alone. But, it is nice to see all the measurements trend downward as I lose weight.At it up quickly and synched to my iPhone. Had some odd metrics at first but a call to support solved the problem quickly and professionally.The metrics and accuracy are amazing…validated the weight with another scale. As a very fit but brittle diabetic, I’m extremely interested in managing my body composition to help manage my blood sugar. A competing scale I’ve had for about four years only offered a fraction of the metrics, which, although adequate, was still not what I needed. So far, this is much more closely aligned with my health needs.This is not a scale. It is a “tool”, a "knowledge box". It is a source, fountain of much needed information. In today’s high-tech world, we need all the information that is available, and this tool delivers 100% percent all the time. Consistently, it gives you more information that what your Dr. knows, and will let you know. For the health enthusiast and the serious athlete, this tool is a must have. It has changed my outlook on my health status, and has me doing research on topics it measures that I was not aware of before.It has changed my outlook on how to take care of this lean, loving, performing machine, which is my body. I totally recommend this device if you are serious about getting to know and taking care of yourself. It is a must have. And for the ongoing price, there is no excuse to not have it. Once you get it, download the app and you will see what I am talking about, and you will never “weight” yourself again the same way you used to. It is not your daddy’s Oldsmobile anymore. It is the future of how to weight yourself and how to analyze yourself. It will trigger you to make more, better informed health decisions, so that you can live longer and healthier life. It is a must have! Get it today and live a much informed, better, healthier life tomorrow. You will not be disappointed!Works well & love the descriptions & breakdown of each category & easy to understand. My weight loss journey is better because of this scale.Purchased this scale about 4 months ago as I was in the beginning stages of another attempt at altering my lifestyle to be more health conscious. I must say I'm impressed by just about everything.Pros:- Great scale for a great price- easy to use app with the ability to track upwards of 8 different people- breakdowns of just about every statistic you could want which is great for those of us who like statistics :)- graphs so you can visually see your progress towards your goalsCons:- my scale measures heavy. After using a scale at a doctor's office & comparing it with my own it actually ended up measuring about 5 pounds heavy which is why I gave it a 4* for accuracy.Overall I would highly recommend this scale. I know several other people whom have the same one & are very happy with their purchases as well. My only recommendation would be that if you have the opportunity to try & compare it with a scale somewhere that has to be calibrated regularly to see how accurate it is. Just my 2 cents.Works as it should.
