I have for sale a 'Supertooth Buddy' handsfree visor kit.
For details see here
http://www.supertooth.net/EN/buddyspecs.htm.Only used for a week. Works perfectly with terrific sound clarity both ways. I have been using it in a Transit van at motorway speeds and can hear and be heard clearly.
Pairs with two phones at the same time, so if you are like me and have a business phone and a personal phone you can have them both on the same hands free.
Selling because the firm has just bought me one
Looking for £40
