The flash is based on its value for money really, really good. The processing and packaging are valent than would be expected on it for that price. And most importantly, that the battery compartment is really good and works better than in the comparable Metz flash.
The TTL function works perfectly on my Olympus PEN, while the photos with the DI 466 is very well illuminated. The charging time with Eneloop batteries is quite fast and is sufficient for most applications.
What impressed me most was the slave function, because this really works well and without errors.
Class flash at an affordable price!
