Good approach, but still rework necessary

Anticipation, the device works perfectly. The receiver sensitivity is good even in difficult situations, the resolution of 1 Hz is sufficient for cycling more like. For Geocaching it should be something more. The chipset can resolve my knowledge to 5 Hz.

Criticisms:
The graphical speedometer is no longer like a joke, and may well be quite fun for 12-year old. A utility does not. Unfortunately, so far too much space is wasted and the advertisements for current speed and distance traveled are displayed too small. Especially on the road bike is missing so that the rapid acquisition and reading requires far too much attention is missing then by road. I still have a conventional bicycle computer and even though its display is not even half the size, can be there velocity and displacement by the greater numbers much better read. I would appreciate it if there is a mode without these graphic frills, but are in future firmware updates with larger numbers.

Point two: The bike mount, particularly the locking tab does not confidence-inspiring impression. I doubt that the device can keep you safe in the long run this mini flap with the mini ratchet. Especially offroad I have my doubts. Here is just a bike mount. Then replacement is announced for a second bike (EUR 15 and not currently available)

Point three:
Software error in ezTour. The average speed is calculated incorrectly in the update of the software. It is used, the total duration of the tour to calculate, not the time on the move! So all traffic stops and coffee breaks going into the calculation. The instrument itself shows the average speed correctly.

For Google Maps in ezTour an account with Google is required. If you have not, the program gives misleading error messages.
A highly recommended tool for this device not only is GPSBabel (To convert the various formats)

The instrument itself deserves 4 points. Cutting back there by these unnecessary graphic gimmick and with the filigree bike mount.
