recommended client for Perfecticus Fighter?

what's the recommended client for Perfecticus Fighter?

 

There's only one, NeXus iBot.

 

And how do I use it?

 

There's a good tutorial here.

 

You don't need ibot if you got an auth code.

 

You always need iBot, iBot is the client. iBot PRO is the pay per month service.

It's a global client, all nexus resellers use that.
