Have tested it with my Nexus 4, Nexus 5 and Nexus 7 and all work wonderfully, even with Case (which may possibly lead to problems with thicker Cases, I had, however, no).
Despite the price, the device acts by no means cheap, it comes here, although much plastic used, but the process works well, and you also do not feel as if after a short time already give up the ghost device.
I welcome also the very discreetly lit LED which informs whether the device lying thereon is loaded.
So you can for example easily be lying in the bedroom.
Also an issue described in another review Spulenfiepen I can not make out, even if I go directly to the device to my ear, you can hear nothing.
I am very happy with it and I've already ordered a second one for work, at the price / performance ratio, you can not go wrong in my opinion
