Honest reaction after a week of use: Dedup pass only flagged 1.2% — cleanest dataset I've worked with. Bought it for our custom software development companie outreach in Australia. One column I'd add next refresh: secondary email.
Used it for a focused territory. Sample matched live data when I spot-checked random rows. Bought it to underpin a Australia custom software development companie campaign. Acceptable trade-off at this price.
