This is a great stylish mouse for you Vaio. The only problem is that it sometimes connects and lags, but you can solve it by turning it on then off again.
does not work wiiith off OS programs like KILL DISKdut you can use the touch pad
I bought this for my Vaio X. Works great, but for the price, It would have been nice to include a travel pouch. Otherwise a great, mouse that matches the style of the X.
