Why should your Mrs have all the Toys :p
Reading the reviews on Love Honey these are apparently very very good for using with your other half (or by yourself if your single :p ) :D They are charging £9.99 for these (http://www.lovehoney.co.uk/product.cfm?p=15676) and are the same on Ebay. .
Pay roughly £3.50 delivered on Deal extreme! Maybe even buy more than one for a saving and sell some on ebay yourself :)
There are 3 different types to chose from, The Clicker, Wave and Spider! Wavy has best reviews on LoveHoney! :D
