Have brought the battery holder for Pentax K50. My expectations were exceeded positively considering the low price. The holder snaps a well in the battery compartment and the batteries are stuck because nothing wobbles. Since the holder's exposed to mechanical stress, that bothers me the plastic material in any way, must somehow come about this cheap price indeed. Thanks 4 Eneloops with 2550 mAh, I now have a whopping 9800 mAh available. The Pentax battery has a capacity of 1050 mAh and is carried only as an emergency reserve. With the battery holder and the Eneloops I now manage approximately 3700 photos (RAW + JPG) in the highest quality, at a time! The 1050 mAh battery there were 450 photos ... So from me full marks for this super useful and affordable product.
