This is a really good alternative to the one I had, which was buying a charger from a dedicated store with a price between 30 and 50 euros. It's really not worth that price and the brands take more money than things are worth as we know. This charger, besides being much cheaper is really useful for the time where we use our cameras the most, which is when we're on vacation! Car charger and plugs for all systems, what else could you want? And it is really light, so not so much extra weight in your bag.
If you feel (like I do) that it is not conceivable to pay so much for a simple device, just because it is from the brand "X" or "Y", than this is a good choice.
