The prototype band, which is not quite as sleek as the final Ellu band will be, is far smaller and lighter than a Fitbit Charge.

The band is only 10mm wide and the weight is less than 2 ounces.  This is in contrast to the Fitbit Charge which is about 7 ounces and has a band that is 22mm wide.

The Ellu band is a simple, unimposing device.  We think this is a critical feature to it being used–we designed it to be small, light-weight and comfortable on the user’s wrist.

Please note that the prototype differs greatly from our final design.  In particular, the band will be much better in the final version.
