The concept is actually genius. The DX-ECO has a gold capacitor (which by design stores power temporarily) that can be fully charged in 3 minutes. The capacitor can then power this wireless 1600 DPI mouse for a full day. A 24 hour charge in just three minutes and you can do this a rated 100,000 times. This makes the DX-ECO one of the most environmentally friendly items ever. That is 273+ years of operation, or at least until we stop using mice.
The DX-ECO also works on nearly any surface, is fully plug-n-play, and is designed to be portable (receiver fits in cradle on bottom of mouse), all for an MSRP or $39.99. For the first time, “Batteries Not Included” is a good thing.
