The CupFone Extension is the perfect accessory for anyone looking for a better position for their mobile phone. The CupFone extension allows you to position your phone in a more comfortable location, and adds greater flexibility to all vehicles. If your cup-holders are too close to your side, then the CupFone Extension better positions your mobile phone up to 4" farther away from you. If your cup-holders too far away and hard to reach, then easily position your mobile phone up to 4" closer. If your cup-holders sit too low, then easily raises the position from an adjustable 1" to 4" higher.
