Hello the Teasi per pulse and speed have ordered blind and am actually completely satisfied. The Navi could be taken and used without a PC. (Had it sent me the Navi in the resort) The menu structure is intuitive to use, the sensors have been found immediately. Had only problems with the cadence sensor (own stupidity). Have the Hotline called, immediately came by and was then recalled on the phone so I standing next to bicycle. Navi has super helped me in France Holidays and led me to the destination. Altitude were displayed correctly, Distance agreed. Tours could be planned. The cycling computer is also fulfilled all my wishes. So now to actually. The software could be better, you have to import the stored tours bit awkward only in an open street map progam.
