I somehow managed to misplace the battery pack for my Sony Alpha 700 camera and really needed to buy a replacement for it. It hadn't crossed my mind to buy another battery pack from a different producer, and not an original Sony product. However, I saw that the search gave me several options and some of them a lot cheaper than the Sony product, so I thought I would at least investigate and see if those options were reliable.
Although I was very reluctant to venture into buying a replacement brand I had never heard of, the two year warranty gave me enough reason to trust the German manufacturer and give it a try.
The product was delivered very fast (and I could start using my camera again immediately!) and it fit perfectly with my camera. I haven't noticed any difference in the quality of the performance of the battery pack as opposed to the original and it lasts just as long. It also is true to the description offered on the Amazon page, so it proved to be reliable after all.
I recommend this manufacturer for the great quality of the alternative solution they offer, at a very good price. It saved me some time and some money!
