As for the look of the unit, it's not exactly high design (it's largely made of plastic), but it's functional and doesn't take up too much space. If you have black Xbox 360 controllers, you get an all-black aesthetic going, which gives the Power Pyramid an even cleaner look. We also liked how the two blue LEDs light up at the top of the pyramid when you're charging the PS3 controllers (there's also a red LED that lights up at the connection point).
For some reason none of the LEDs lit up when we were just charging the Xbox 360 controller. But the green ring on the Xbox 360 controller was pulsating, so we knew it was charging. PS3 controllers take about 3 hours to charge, and 360 controllers take about 6 hours. (Konnet says there's an "Intelligent Protection System" built into the charger that helps you avoid over-charging).
Aside from the mysterious LED situation, we had one other gripe: the price. The PS3/Xbox 360 Power Pyramid lists for $50, which just seems a bit high. We like to see ) in the $20 to $35 range. Sure, the convenience of being able to charge both 360 and PS3 controllers is worth paying a premium--but $50 still seems a bit steep.
Hopefully, we'll see a few bucks shaved off it, because at the right price, it's an appealing accessory that should find a market with dual-console owners. Now if Konnet would only add slots for Wii controller charging, you'd have the ultimate charging dock for multi-console households.
