DON'T GET THE DC-610, it sucks, the DT-910 is better although not that great anyway.
If you wonder why I think the dt-610 sucks, it is because the charge area is so tiny that I have found myself changing the position of my 920 in order to charge it, I used to have the DT 910 and it was a lot simpler but as a con, it takes longer to fully charge my 920.
DT 610 ~ 3 hours to charge
DT 910 ~ 3 1/2 hours to charge
Regular wired charger ~ 1 1/2 hours to charge.
I see the convenience of the wireless chargers but for now, from the ones I have owned I can't say the can replace a regular charger.
