So I use since long time batteries. The acquisition was necessary because I shoot a lot with external flash and the matter therefore worth quickly. I have taken the same 2400 mAh battery to do so. Seemed quite favorable. They were as good summoned, that I was able to run through a whole Fotoseassion. Cool. So to get an intelligent device for the price that was 10 years ago, a childhood dream. I got also have 2-year-old Ansmann batteries again by the discharge-charge function fit again. In another charger was there an have been named as 'defective'. Previously, I had tried to charge the batteries with a 10 year old Sony charger. Everything is now ok to my delight. Not so good, I find: - The fact that the display backlight is always on, but does not bother me. - That the batteries are not so easy rauszubekommen. - What annoys me animal now, is that I individually the 2400 mAh battery no longer get different capacities and one should not mix indeed. Now I have to divide them into two divisions my "Battery Fleet". These manufacturers never think about something after.
Nevertheless, there are 5 stars because it's super compact and me also the individual control of the shafts was very important. Would I buy again and also recommend it.
