I saw the great deal on this combo 2 pack batteries + charger and grabbed 2 sets. The charger is working well, but it is not one of those fast chargers. Take about 3-4 hours to fully charge a battery. I wish the charger could do 2 batteries at the same time, since they include 2 batteries in the combo (that would have been nice). So, I have tried both the Wasabi branded batteries and the Ricoh batteries and the charger has worked well with both. As far as the quality of the Wasabi batteries, I am not seeing much difference in length of charge time from the original Ricoh batteries (maybe just a tad less, but i'm basing this on the amount of photos I take per full battery charge). This will be different for everyone since some people chimp and play with the settings and others just shoot. I would say they are a good value for the cost. If you are shooting with a GR3/3X then you already know this camera likes to eat battery like a V8 eats gas. At this cost, buy a few, I bought 2 sets so I have 4 extra batteries and an extra charger if one stops working for some reason. Its plenty to get me through what I need. In conclusion, I think this product will be useful to most people out there. You can't really beat the cost. I am happy, and would comfortably recommend this to someone looking for a backup solution.
