It is very easy to use, it works well with all browsers (even mobile devices), so I can be sure that my clients are safe when they access their website from anywhere in the world! The price for this service is not cheap at $50 per month.
If you want an effective copy protection solution then go ahead - but if your budget allows me would recommend looking into other services/products out there which offer better value for money. We have been able to provide our client base worldwide secure copies of websites without them having to worry about viruses or malware being downloaded onto computers while accessing via public internet connections.
