Speedbox 2 experiences?

Does anybody have any experiences using the Speedbox 2?

It seems to be more sophisticated than the Badass, potentially higher speed with assistance, correct speed displayed and ability to link to a very smart phone app (at a very high price).

I'm enquiring for a friend who has heard that it gives the correct speed in km/h but not mph which seems strange. Maybe it only works correctly with certain Bosch bike computers?

a dongle only removes the speed limit it wont give you any more power and is the same for all dongles.

Thanks for that link, very interesting. Point taken about the power assistance,

Do people find they run out of gears using these things to their full advantage, I imagine ebike gearing is optimised for 10-15mph rather than 20+mph?

18-20t at front 30mph+
