I bought a cheap second battery for my Canon EOS 1100D me this battery. The original cost you many times more. In addition, stands on the original battery indeed made in China it. So I'm assuming that the Chinese had in between enough time to copy the battery properly or even improve. I noticed the lower weight of the bundle Star battery. It weighs 40.6 grams and 45.3 grams of original battery. The battery is absolutely perfect fit and there are purely external to detect any differences in the housing. Only the label is slightly different, showing the label of Patona. This company can be found even among the de address on the Internet. Focus is on the mobile energy, where it has established itself as a leading brand by its own account. Anyway, I can fully confirm the good quality of this battery. He is the power of the original in any way by or possibly even exceed them (you would have to accurately measure). Conclusion: Top battery at a reasonable price - just buy it!
