Very good lever for a more than fair price:

I ordered two controllers, both work simultaneously on an Android case. The 2.4Ghz wireless USB dongle ensures there is no lag time in movements opposed to blutooth found on other controllers.
But (1) one of the two joysticks had only a very limited scope (against more than 10 meters for the second) and I therefore returned for exchange. And (2) it is difficult, indeed, to know when the charge is complete with a handle (count sixty to ninety minutes for a full charge).
