module where you don't have to create account

[tommy11011]

All,

 

I know there is module that will allow you the option to not have to create a user account and simply let you enter the minimum info to buy a product.

 

I was wondering if anyone who decided to use it noticed any type of increase or decrease in sales. I'm debating whether to use this or not.

 

Also, did anyone notice any performance increases after adding the module?

 

Also, how intrusive is the module install? How does it effect site design if the design is heavily modified?

 

thanks
