What to know before buying

Listing details to confirm

The title lists 75 x 60 inches, while the product dimensions and selected size list 75 inches long by 57 inches wide. Confirm the supplied panel dimensions and fit before ordering. The listing also uses the malformed opacity value "Blackout inches" and claims 100% blackout without independent performance details. Adhesive longevity is not assured by the listing, and customer feedback on it is mixed.

Customer feedback reports useful light blocking, relatively easy installation, cut-to-fit convenience and some cooling effect. Those points align with the product’s blackout and cuttable design, but the practical outcome depends on fit. Adhesion and durability experiences are mixed, including both strong sticking and reports that the cover came down quickly. Value opinions are also mixed, so buyers who need dependable long-term mounting should weigh that uncertainty.

Positive themes

Customers report effective light blocking and ease of installation.
Some customers describe the panel as easy to cut and say it helps keep rooms cooler.

Mixed feedback

Adhesion and durability reports range from strong sticking to pads failing and the cover falling soon after installation.
Customer assessments of value for money are mixed.

Frequently asked questions

What size is this cover?

The title says 75 x 60 inches, but the listed dimensions are 75 inches long by 57 inches wide. Confirm the selected listing’s actual panel size before buying.

Can it be trimmed?

The manufacturer says it can be cut for a tailored fit, including for irregular window and door shapes.

How is it attached?

The listing describes hook-and-loop adhesive tapes for drill-free installation. Customer feedback on adhesion is mixed, so the attachment may not suit buyers needing assured long-term retention.

Is the product guaranteed to block all light?

The manufacturer claims 100% blackout, but the supplied opacity field is malformed and the claim is not independently verified. Actual results can depend on fit and light gaps.
