I saw this in a store and checked it out. I replaced the product, walked over to the Velcro cable management ties ( Cables To Go - 29856 - 11in Velcro Hook and Loop Cable Straps Bright Multi-Color 12Pk ) and saved myself $96, plus ~$20 per extra device for which I would need to buy an adapter. Attach a Velcro strap to each recharge cable, wrap it, and then PUT IT AWAY when done. BUT, WAIT! THERE'S MORE! If you buy now, you'll be able to keep the cable wrapped, WHILE CHARGING, at no additional cost!
Frankly, these recharge pads save no extra electricity, and are NO MORE CONVENIENT. The pad uses an much electricity in standby mode as my cable does, but i'm quite certain people will leave the pad charged in at all hours, whereas they would normally unplug the recharge cable when done. You still have to plug your device in to something. The pad takes up space and is nothing more than neat-o gadgetry for people needing an ego boost.
What we REALLY need is for the IEEE to decide on a standard, external recharge pin configuration or induction charging solution, which manufacturers may integrate into rechargable products (phones, cameras, entertainment devices, hearing aids, etc). This way, you'll never need attachments, and charging pads will be standard features in nightstands, desks, kitchen counters, etc.
