Any experience of Cloak Hosting?

Hi

I'm just wondering if any of you have had experience with Cloak hosting dot com? Good or bad? I don't want to migrate all my sites there only to be penalised by google...

I've read a thread posted last year on them here:

and I can see there have been recommendations too...http://www.blackhatworld.com/blackhat-seo/blackhat-lounge/789265-hostwinds-ip-privacy-service.html but I would have expected more chat about them on bhw if they offer as useful a service as they claim.

Have you had experience of them? thanks
