The Teasi makes not only on the bike looks good, but also offers features that are very useful and interesting as you trek in (not only) unfamiliar surroundings. In addition to the detailed map I particularly like the customizable display of the computer view. I think it's great that I can decide what I tells the computer while on a tour. The only deduction I would do with the software, which is, however, not included and hence will not affect the rating. Just FYI: The registration runs cumbersome and the representation of the recorded tour is not as extensive / user-friendly as the Teasi the suggests.
