Life Leads Direct

I'm looking to purchase several thousand in aged leads, and I came across this outfit. Has anybody had a positive/negative experience with them? I have a marketing plan in place for the aged leads, just looking for feedback on the company. I understand there will more than likely be junk in the mix, but I like the information they provide with their leads. TIA.
The leads are not scrubbed for the Do Not Call List. And they are too old to be exempt. So just good for door knocking or as a mail list and hope they respond.
Interested to see how you went with these? You can still scrub the list. Are you allowed to sms them?
