These samples got tested almost to destruction as we're a boating family and know what we would put them through! Honestly very impressed. The foam is tough enough to stand up to a lot of punishment, even deliberately dragging ropes across it, scuffing shoes on it, it came through the lot.The adhesive does not mess around! That was our biggest worry, but once down these did not want to budge even a little. They seem water resistant, but we haven't been able to try them with salt water as yet.Good range of colours that are neutral enough to compliment most vessels, not very many patterns to choose from though. Would have liked to see something more high-grip. They do look good though, and certainly do the job!
