Inclusion rule
Case is publicly published on letsgetwrap.com and states brand, model and material.

Known limitations (quote these with the numbers)

  • This is an in-house installation sample, not a Hong Kong market study, market-share estimate or average market price.
  • It is not a laboratory performance test of any film; durability claims are not inferred from this data.
  • Individual completion months are not published per case, so no time-series or trend conclusions are drawn.
  • The sample skews towards vehicles whose owners agreed to photography and publication.

What this report does not claim

  • No estimate of Hong Kong market size, market share or average market price.
  • No laboratory performance testing of any film.
  • No durability or warranty term inferred from the sample.
  • No ranking or comparison against other shops or brands.
