I let myself be tempted by these Varta batteries during a flash sale within 9 to test. They are not too bad, but do not compete, by far, my references are the Sanyo eneloop batteries. My Sanyo do "only" 1900 mAh and much better fit in the time and in the operation that these Varta. At first I thought it was because they were new. But after six months ... Whether in a Wiimote in a camera or my flash, the eneloop do much better for the same price despite lower display power.
