Finally. The most accurate scale possible to help me measure between quarterly DEXISCAN appointments. So easy to use and the metrics are bomb. Easy to download information (I download the full scan into AI to dial in). I am most satisfied as the last scale was way off. The only additional benefit would be if they added an "athlete" mode, but even without this scale is the best.
Honestly, this scale is awesome. I expected shipping to take a while since it was a launch deal, but it arrived in just 4 days. Works perfectly and looks premium. Glad I grabbed it early — I checked today and the price already went up.
Way better than I expected!
I was honestly surprised by how good this scale is, and I love that everyone in my family can have their own profile. Now it’s become part of our morning routine — we all step on the scale right after waking up to see how our numbers change day by day. Totally exceeded my expectations!
It lets me know exactly what I areas to work on to reach my goals. It shows BMI, Bone, water, body lay out of areas that have different levels of muscle mass. Love the the charts show declines or raises in weight.
It's extremely sensitive and I'm looking forward to gaining strength and loosing weight with bad fat. My trainer is pretty happy about it too. It will assist him with my journey
The scale does not have athlete mode, which was a bummer. The scale is great except BF%, If you lift weights or carry a lot of muscle, the BF will be off. But other than that great scale!
I like all the quality features and things that are above normal from a standard scale on body measurements and things like that. My one gripe is about the multiple user functionality. Everybody has their own smart phone these days and wants their data recorded on their own device. having to use one device or disconnect, Bluetooth from one device to the other is really quite a nuisance. We’ve had our data reset where it’s registering. The main user on both phones and that weight isn’t really capturing properly and it’s frustrating because we’re having to reset our progress.
