Query: perfect for small office - bluetooth skype and mobile phone connection

Fantastic product for anyone that wants to conference via skype or cell/mobile phone.The bluetooth function works reliably whether connecting to my macbook or iphone.Note this device does not have a auto switching power supply, the 120v version self destruct if you use with 220/240v.Works well with a 50w 240 -120v step down transformer
