yes, they r working very good.. I also used these kind of software... But I did not buy it i use free..

By this help of this software - i can easily make 2000 gmail account per day.. and i also sell them regularly... for 1000 gmail account = $ 14.00- $15.00 - they paid me ...... So, I can make money easily .........
But I wonder then why you are not mentioning the software name here, nor you have given any link of the software. Hope you give it now.

Anyway, I wonder why some people wants to have so may gmail accounts say 1000 or 5000. What they benefit out of it?
