With its sleek white finish, its bright blue "on" light and even its little stand, the RocketFM looks the business.
Unfortunately, its performance leaves a lot to be desired. Range is much lower than the 10 - 30 foot claimed by the manufacturer -- more like 10 maximum. And when you factor in the odd wall or door (which is probably why you opted not to use cables in the first place) its even less than that.
Even at close range heavy bass is distorted as a result of the FM transmitter.
The software is simple and works well and the thing makes a great desk accessory, but for anything other than background music you might want to find a higher fidelity solution.
