## Less suited to

- Anyone needing independently verified performance or confirmed package contents before purchase.

## Customer feedback

Aggregate customer ratings lean positive, with most ratings in the five-star category, but lower ratings are also present. Without written feedback, the ratings do not show what buyers liked or disliked. Treat them as a limited indication of reported satisfaction, not confirmation of smoke output, leak sensitivity, or kit contents.
