Size of the new device
I read that we now get a bigger battery thanks you for that at first place

Second you say the device gets bigger arenthe actually showing size parameters on the website the new onenor the old one ?
We've already updated the product pages with the new size:
53.2(H) x 26.7(W) x 16.1(D) mm including clip

And now we're working on optimizing the size once again, especially for decreasing the height. The final version will be smaller than ES100 anyway.

Thank you!
