What to know before buying

Listing details to confirm

The manufacturer describes this as supplementary windscreen support, not a replacement for a built-in car heater. It claims help with frost, light ice and fog, but does not establish whole-cabin heating performance.

The supplied rating information is entirely five-star, but the sample is small and there is no written customer feedback to explain the scores. It cannot establish how well the heater clears a windscreen or performs in use. Buyers should weigh the rating cautiously alongside the stated 150 Watts, socket requirement and 40-minute continuous-heating limit.
