Survey Methodology and Data Sources

Between January 1 and March 31 2025, LexyFill aggregated 500 verified user reviews from three primary channels: the official product website (315 responses), Amazon US (124 responses) and Trustpilot (61 responses).

The data set includes 312 five‑star entries, providing a robust sample for statistical analysis.
