    • A terrific buy! Think you need one!
Size: 11.02"/280mm
Such a great scale for a great price. Have told several people about this and three have already purchased. Gives you lots of great info including BMI, cardio info, etc. Everyone should have this or similar!

    • Seems accurate. App is solid.
Size: 11.02"/280mm
I've contemplated purchasing a smart scale fort over a year. Almost went for one of the ~$200 big brands on several occasions. Reviews of these are often not great. Even the big dog that rhymes with fume gets some negative remarks. I saw this scale for sub $40, and had a 4.7 rating. Most of the reviews mention seemless app syncing, which is a negative mark with many smart scales. Accuracy also was often noted. I decided to pull the trigger. Firstly, as a scale it is dead accurate. I have a digital Taylor scale that can vary 4 or 5 pounds every time I step on it. It's a top brand scale, and cost about what this smart scale costs. This scale does so much more, too. I can't say that every body measurement is completely accurate, but it is consistent, and shows actual variance in measurements when I drop a pound or two. Plus, it tracks your progress. The consistency makes it a reliable tool. One side note. I spent a day swimming, and got on this scale a bit later in the day, and it told me my feet were too dry, lol. I lotioned them, and it worked fine. I would say for this price point, you can not go wrong. ... show more

    • I like!
Size: 11.02"/280mm
As a postpartum momma who is actively trying to get back to pre-baby weight, I needed a scale to help track my progress and this scale has been perfect for that. It was easy to download the app and connect it to the scale. You do have to have the app open near the scale in order for it to read or record your new measurements every time. Overall, it was a good purchase, it does everything I needed it to, and I’m glad that I bought it ... show more

Outstanding customer service. When the original unit had an issue, the seller communicated immediately and went far above and beyond to make it right by providing an upgraded replacement. Fast shipping, responsive communication, and truly top-tier support. A+ seller.
