What to know before buying

Listing details to confirm

Listing details are inconsistent: the title says 5m, while the stated item length is 15 Feet. The Italian model wording describes the cable as flat and nylon, while the title says braided and the feature text calls the braided covering cotton. Confirm the selected listing's length and construction before purchase. The claimed 40 Gigabits Per Second and 2000 MHz are not independently verified and do not establish the speed supported by connected equipment or the internet service.

Customer feedback describes the cable as well made and says its flat profile is convenient for routing along skirting boards or beneath carpets. Customers also report stable connections for gaming and streaming, with individual examples mentioning 2.5gbps and 970mbps. These reports suggest it may suit tidy indoor wired connections, but they do not verify the listing's higher 40 Gigabits Per Second claim. Aggregate ratings are mostly in the top categories, though ratings alone do not establish a specific performance outcome.
