If you are talking about a dialer that calls a 1000+ numbers a day and when the person answers a pre-recorded message comes on don't do it!!! I tried after a week of hang-ups and cussings not to mention a cop showing up at my door I sent it back.
That was over a year ago and I am still waiting to get my money back. If u do then don't go through cheapautodialers.com, he is a crook!!!
As soon as I punched enter I wanted to take that crook statement back but the reason I am calling him a crook is because he has (or had) a 30 day money back guarantee and he was all smiles and how can I help you until he got my money then after about the third call to him because I needed technical advice he started to get short with me. I told him from the start that I was a computer *** and he assured me that he would be patient with me. After about a week of aggravation(I had 4 lines installed to call with)I boxed it up and sent it back.. He has yet to send me my money, I contacted him I contacted the Houston BBB and they have had other complaints on him also.
As far as the cop, when the dialer calls a residential home my # showed up on their caller id so they called the sheriff's dept. and they came to my office and let me know that this person was very upset and she was on a Do Not Call list. I assured him that it would NEVER happen again. That taught me to personally scrub each and every # that I dial.
