Have never used them, and would never use them

Think about it, what purpose other than personal vanity does buying in random traffic achieve?

If you are selling a product or service, random traffic is actually irrelevant. You want targeted traffic that stands a chance of using your services or generating leads.

Better to get 100 visitors a day and generate 20 leads, rather than paying for 1000 visitors a day and generating 10.

If you are looking at spending money to generate targeted traffic, then consider something like adwords.

Hey linastylist, I thought the same thing...doesn't cost much, so "what have I got to lose?" 

Well, I went and signed up earlier this year, (The clean fresh website got me) asked some questions (without reply) waited a little longer, wrote to them a few more times, a month later got an email apologising for the late reply, then I thought I would give them the "benefit of the doubt", but months later now, and still nothing! I'm just lucky I bought the cheapest one they had to offer ($20 for 25,000 hits..I think) I can now safely say that it is a scam! It's hard to get good traffic, and frustration brings on desperation! (Trust the Gut Instinct!) Not a big $ loss, but if a few thousand people sign up, then its money for jam for them, and they would know that most people won't try and chase back such a small fee. Please learn from my mistake and Dodge Them!

Perfectly valid point. You need to be focused on the quality of your traffic. I know it's hard... but the marketing is not an easy and straight-forward thing, although these services can promise you otherwise
