Based on a thorough analysis of these 11 reviews, the overwhelming majority appear to be genuine customer experiences. With 10 out of 11 reviews being verified purchases (indicated by 'V'), this significantly increases the likelihood of authenticity. The reviews display a natural distribution of ratings (mostly 5-star with some 4-star and one 3-star), which is typical for a product that generally meets customer expectations. The overall impression is of authentic feedback from real users who have applied this grout sealer in various home improvement contexts.

Strong evidence of authenticity appears throughout the reviews. Review #1 provides detailed personal context about a shower retiling project, describing the product as a 'game-changer' with specific application details. Review #6 offers balanced feedback, praising the product's ease of application while noting durability concerns after several months of heavy use in a shower environment. Review #7 shares a specific timeline ('Did this in March and it still looks brand new'), while Review #8 mentions a concrete problem solved ('stopped the shower bottom tiles from getting water behind them'). These reviews contain the kind of specific, contextual details that are difficult to fabricate and indicate genuine usage experiences.

Only minimal concerns exist, primarily with Review #3, which is extremely brief and generic ('Easy to apply'), and Review #10, which is in Swedish and similarly brief. However, even these short reviews could represent genuine users who simply didn't elaborate. There are no clear patterns of marketing language, repetitive phrasing across multiple reviews, or other manipulation indicators. The presence of a 3-star review (#5: 'didn’t see much difference') further supports authenticity, as fake review campaigns typically avoid negative or neutral ratings.

In summary, this appears to be a collection of predominantly genuine reviews for a product that generally performs well. The verified purchase status, detailed personal experiences, balanced feedback including minor criticisms, and natural rating distribution all point toward authenticity. While a couple of reviews are brief enough to warrant mild scrutiny, they don't display clear manipulation patterns. The overall fake percentage is estimated to be low, reflecting that most reviews show strong indicators of genuine customer experiences.

Key patterns identified in the review analysis include: Verified purchase status (10/11 reviews), Specific application contexts (shower retiling, bathroom renovations), Balanced feedback including durability concerns.
