What customers say
Customer feedback centers on the Duotrap S Cover's dual nature: preserving the sleek look of carbon frames while presenting retention issues. Users value how well it seals the sensor cavity against dirt and moisture, maintaining aesthetic integrity. However, satisfaction is significantly lowered by the cover's durability and fit. Many report the piece loosens or falls out easily, forcing frequent, unexpected replacements. This recurring problem, combined with the high proprietary cost for a small plastic component, leads reviewers to question the overall value proposition. While its protective utility is clear, the poor retention and expense temper enthusiasm.
