1. The design is more fashion with shining silver side, add some element of metal.
2. The solution has 3 coils inside, it makes the charging area much bigger than 1 coil solution. Any place on this pad is the sweet spot so you can just put the phone on the pad and it starts charging, very convenient.
This pad seems too smooth to place the Nexus 4 like the old version, if the table is not very flat, it will slide a little bit. But it has no problem of draining battery after charging complete. And it generates less heat than most other brands, never higher than 104 °F.
