One2 The Teasi I have now for 6 months and have it used in Germany and in Italy for road cycling. Even walking in the big city, I do not want to miss the Teasi. The POI contained always help a restaurant or other Pnukte of interest to find. With the right system settings you're making good progress. Of course, the device does not run exactly the route that you would prefer in a familiar environment, but that does not Navi, neither the car nor an outdoor unit. You can circumvent this by previous careful route planning and dubbing on the device. The possibilities of the route recording and documentation of the training values are just fine and are the possibilities offered by more expensive devices that barely nach.Das diplay is bright enough and of excellent Detailltreue under almost all conditions. Natürlch the battery could last longer, because after about 6 hours is not much there, but also here you can get out with the right system settings a lot, or connect an external battery or tap the Dynamo. I would particularly like to highlight the continuous improvement of the software. You can feel that there's someone cares and does not want to miss out.
