LG WCD-100 Qi charger purchase

I bought a ZENS charger a while back, but the high temperature compared to using microUSB has put me off using it on devices with built in batteries, as I am convinced the high temperature WILL reduce the battery's lifetime.

Today I watched some YouTube videos about the LG Orb charger, but ended up buying a WCD-100 which is designed by LG for their G3, from CD-ON for kr. 299. The orbs cost closer to 500.-, not a price I wished to pay.

I tried the G3 on the ZENS, but I think it is on the edge of providing the right level of power.
