# Sumobaby Portable Blackout Window Cover, 75 x 57 in

Sumobaby portable blackout window cover is a cut-to-fit, no-drill shade made for windows and doors. Its hook-and-loop tape installation and portable format may suit temporary or irregular openings, but the adhesive’s staying power is a reported point of mixed customer experience.

## At a glance

- Listing describes 25 square hook-and-loop tapes for drill-free attachment.
- The panel is described as cuttable for windows, doors, skylights, RVs and other irregular openings.
- The manufacturer claims a reflective silver coating and high-density black polyester backing for light blocking and heat insulation.
- Lightweight, portable design is claimed for transport and temporary use.

## Pros

- Cut-to-fit construction offers flexibility for openings that do not match standard shade dimensions.
- No-drill tape attachment avoids the need for drilled mounting points.
- Portable format can be useful for temporary shading or travel.

## Cons

- Adhesion is a meaningful trade-off: customer feedback includes reports of pads failing and the cover falling, alongside reports of strong sticking.

## Before you buy

- 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.

## In the box

- User manual (Included)

## A good fit for

- Buyers seeking a portable, cut-to-size blackout cover for a window, door or irregular opening.
- Renters or temporary setups where avoiding drilled installation is useful.

## Less suited to

- Buyers who need a precisely specified standard blind or a clearly established long-term mounting method.
- Anyone who cannot accept cutting the panel to fit or the uncertainty around adhesive retention.

## Customer feedback

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.
- Positive themes: 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.
- Mixed feedback: 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.
