For Elinchrom Skyport users with IT / RX compatible Speedlights I think there is nothing better, but also Skyport Universal user he is raising with the Skyport only their wireless flashes ideal because it has a directly integrated Skyport Module.
The battery I do not see as negative as others. One short screw the lid on, sets the battery and screwed again .. I think the whole not even takes 60sec. For this you can load it with many cell phone chargers, or even directly on the computer .. In the event that the supplied charger was forgotten times at home .. Clear were ordinary AA batteries also nice but that would make the device more difficult (is really incredibly easy) and one must say that the fully charged battery lasts already pretty long. So you can already Calibrate some shootings before one would first recharge.
Also I hold the rotating ring above the dome not for too sluggish. It is tight but I think that is an advantage rather than a disadvantage because he just sits so tightly that the cap does not retract again. Perhaps you know the cost of zoom when the camera hangs down moves the zoom suddenly automatically. In expensive zooms this rarely happens. It's the same in the ring. Check it out yourself time, I hold him in any case for quite ok.
The surface and the entire unit will not be insensitive, but devices with TFT display and measuring instruments at all you should not anyway better drop.
The default setting is in 1-stop increments, it may cost 10-20sec going to the menu and to change it from all apertures to 1/3 stop. This is done only once and then it's in there forever until it is changed again. Something should really no negative point represent because in the camera one goes surely also times briefly into the menu when you have new and provides everything one on his desires. At least, this meter 1/2 and 1/3 stops and fits perfectly to the settings which can convert all major digital cameras.
The price is not without for the small device but from me a clear recommendation, especially for ELINCHROM users.
For general use of light meters today: It is indeed often the display used to replace light meters. I was therefore also usually cope but can say that a reasonable turned sonable lightsetup often afterwards again more leeway up and down in the Raw Files can. What then was so makes nowadays in digital still a lot of sense for analog duty.
