The receiver is easy to use and works reliably. Unfortunately priced lifted somewhat when you consider that in almost every cell phone, a GPS chip installed. One criticism is the observed deviation of the measured GPS location. This is always constant about 20 m east of the actual location with me. Allegedly, in the tolerance of the relevant standard ... Compared to GPS phones, the question to Canon: Why these tolerances do not exist in GPDS modules of brand mobile phones ??? Something unwieldy Also accommodation designed in ordinary camera bags.

I have the energy reserves while never completely depleted, but maybe that's why not, because I have often turned off during the photo session times. But in this context it's what happens also that a photo shot at the fast, without making the switch for the GPS module again ...
Conclusion: Who takes the prize and a post for example in Geosetter in buying and perhaps always dabeihat a spare battery is well served with this accessory.
