Retractable cable， portable notebook best partner 

◆ retractable cable network， the actual length: about 2.5M 

◆ Auto elastic shrink cable (with switch) 

◆ Compact and lightweight 

◆ automatic recovery within a few seconds 

◆ With this retractable cable， would no longer have to travel a long roll with a RJ-45 Ethernet and ISDN network cable to connect the device outlet. Really very convenient.
