Couldn't tell you how accurate it is but it is consistent.

The big selling point of the scale is it's detailed measurements of body fat and muscle mass etc. I have no idea if its very accurate, if I had to guess, its not. BUT it is very consistent so at least you'll have a baseline idea of your muscle gains and fat loss. One of my favorite features is that it can recognize different users. My girlfriend and I both use it and when either of us step on the scale it knows who is using it and stores our information separately. When paired with the Garmin connect app it gives you a great place to track progress over time.

This help me take a lot of weight OFF

I did a lot of reading about it after I got it. And found out the metrics used is based on the average individual 5’9 the number coming up on the body fat was not making sense. So I got my self a caliper and used the parrillo method on http://www.linear-software.com/online.html Got my fat percentage from the caliper and enters it in the scale through the Garmin connect app. I’m 6’2 and pretty muscular on my whole body except the belly and love handles and 37% was way way off. The caliper said I was 24%. So the scale has difficulty with muscle density I guess. Any who. Love the scale I went from 270 to 194 currently I lost a lot more then I wanted since having distal bicep surgery in April of 2025 so I lost a bit of mass but I’m gaining again super lean I hit 6% body fat a couple days ago now just have to dial in the diet to the right ratio to gain some mass back

Very difficult

Very difficult to connect to iPhone, (maybe that’s intentional). My husband got the scale for Christmas, connects to his Garmin watch and android phone perfectly. He wanted to add me, to do so we have spent A LOT of time over different days trying to connect. Now connected, still the stats aren’t showing on my phone. Unbelievable! Probably tomorrow the data will be there… Hopefully, you can improve this for other users.

Works as intended

works well and as intended. I think the metrics are a bit off as the muscle mass and bone mass can vary day to day. but I love that it seamlessly syncs with my Garmin app and the other subsequent connected apps. it is slightly finicky turning it on. I usually have to slide it on the floor or step on and step off.

reply from Care

We are so glad to hear you are liking your new Smart Scale, Tracy! With powering the unit on it looks like you would start by stepping off of the scale and then tap the scale with your foot. A short, sharp tap will turn it on. When the scale wakes up and shows "0.0" you can step on to get your measurements. If this is not helping to wake the scale up you are more than welcome to reach out to our product support team for further assistance. I know you also had some questions about the metrics tracked which they can go into more detail if you would like. Their phone number is 800-800-1020, Press 3 then Press 2. M - F, 7AM - 7PM CTL

Smartest Scale I've ever seen!

This product is tops and is making my health care awareness far more advanced than I could ever imagine. Why did I wait so long? With all the information available, I am making strides to lose weight and maintain my health on a whole new level. I've also added the Blood Pressure cuff.

Great scale and integration with Garmin

The scale is great, BUT the accuracy of the body composition is questionable. Unfortunately, I did the research after the purchase which verified my findings. That said, I did get my body composition measured and plugged those numbers in to calibrate the scale and it seems better now.

For a Garmin user, it’s a breeze to set up!

This smart scale is a replacement for an older Fitbit scale that failed after getting wet. I use Garmin bike computers and smart watches so am familiar with and use daily, Garmin connect. Read the directions, down load the Garmin connect app and put this great smart scale to use.

Weight a minute, it works!

Smart scale integrated with Garmin architecture reduces the hassle. It keeps track of my metrics so I don’t have to. Purchased this scale based on recent health changes and wanted to keep track of more metrics. Training for half-marathon while trying to gain weight as in muscle mass. This scale helps me track progress. On the flip side using Garmin architecture integrated with plug in app data for my dietary tracking. My diet, weight, training, and more all comes together here with Garmin products.

Perfect for tracking my body stats!

Bought this a month ago and I’m pretty impressed! The biometric readings are pretty consistent which is what I was most concerned about before getting this. My main use for this is to help motivate me to get into better shape. There’s nothing like seeing where you’re currently at to motivate you to keep going forward!

3 out of 5 stars review

Confusing

I love the look and the idea of the scale. I am not particularly happy that it sometimes weighs me 4 pounds heavier. I have a very small area to keep a scale so I have to stand it up on its end, like I have done with my old scale. It never weighs me correctly. It adds 4 pounds to my weight. I have to reset it to zero a few times before it gets to weigh me accurately. I have tried to lay it flat and then lift it up to move it to an area I can actually stand on it (like I said, I have a small area in which to put a scale) and it sometimes still adds 4 pounds. I will probably have to return this. It is too expensive not to be accurate.
