I am very confident that none of the software mentioned in this thread is able to generate anywhere close to the amount of working Google proxies that No Hands Proxies is.
And for the record No Hands Proxies does not simply harvest proxies from a simple list of sources (despite having by far the most up to date list of any tool on the market), it will search for new sources so you are not totally reliant on the built in list of up to date sources.
As far as I am aware No Hands Proxies is the only tool that will check proxies whenever they get to a certain age (i.e when they were checked more than X minutes ago) as opposed to re-checking after the whole list has been checked. As a list can take upwards of an hour to test that means with most other tools your proxy list can be an hour+ old when you go to use it whereas with No Hands Proxies your list is only ever as old as you allow it to be.
This is not just sales patter it is the truth and part of the reason for the huge disparity in the effectiveness of No Hands Proxies compared to other tools. I mean you only need to look at the list of users giving their testimony about it in the sales thread, these are not paid off members or influential friends of mine, they are just users that have used No Hands Proxies (and in a lot of cases all other mentioned tools) and saw how different they were in how usable the proxy lists generated were.
