The Best things to check for with a Reverse Phone Look Up are as follows:

* Is the company established?
* Do they have a record of being good with refunds?
* Is their database extensive (you know, BIG, REALLY BIG)?
* Are they pulling any fast ones (like recurring fees for things you don't want)?

If you get the right answers to those questions then you are on the right track with that company. Another thing a few ,OK lots of them, do is tell you they have a free service. Then just as you think you are going to get the info they say, "Oops, we don't have that number, But if you go here or pay this we can definitely find it". For me I won't even do business with a company that pulls those shenanigans.

Even if you don't mind that B.S. you would have to admit that it is a bit sneaky and underhanded. Which leads right back to the reason you are looking for this service in the first place. You know what the reason is. I don't know your situation but I do know why people use this service. Usually its for at least 1 of the following:

* Suspicions of unfaithfulness
* Harassing or Repetitive calls
* Stalkers calling your children or you

Of course there are lots of other reasons but that is the big three at the top of the list. Whatever your situation be assured that you have a 91% chance of getting the information on the number in question. My data varies between 89% and 93% so they are really close in their figures. Get the info you need. Knowledge is Power.
