However, I would point out that I am doing this battery grip with 2 Ansmann LPE8 batteries and perhaps therefore this abnormality. But this bothers eh not particularly because the battery should be sufficient even for a day session, if it is not too hot or cold. Processing would I consider quality and there is also no chemical odor present. The catch is stable and will not budge. Also, the on / off switch is very useful in order to prevent accidental operation. All the keys are working with me and the dial I emfinde even more pleasant than that of the Eos 650D. Yet I speak from a strong buy recommendation, since at this price can not be much wrong.
