I compared the dimensions the other day with the Colibri specs (as I have a Colibri at hand). They’re pretty similar.
In all honesty the Colibri in hand doesn’t feel that different from a usual dongle. Mathematically it might seem a much bigger three dimensional volume than a dongle like the Chronos or Questyle M12/15 - all of which I have at hand to compare in person. But in everyday use it’s not really that different, so I think “slight” is fine for the size description, because that’s how it feels in person. Mojo (which I also have at hand) feels much more substantial and inconvenient for portable use than the Colibri. So if BTR7 is Colibri-sized (which the specs confirm) then I won’t have any problems using it on the go.
