Not sure worth the price ATM
I have owned my Ember device for a few years. Overall I am happy with the package but that’s not to say I have some major concerns: 1) price for the credits, especially after a costly device 2) technical support and app updates. The support team answers questions fast but the updates to the app when there’s an issue take very long to be updated and addressed, leaving one with a useless device for many days. 3) some people have noticed that the Ember device is not FDA approved, therefore the accuracy of it may not be what it claims. The company has yet to address this publicly. If you have the money to spend and what a unique device like this I may see a reason to buy. But this device is similar to many bicycle power meters where you may get an approximate number, not a definite one. And they are both expensive!!
