Storm doors are an easy upgrade for keeping bugs out, letting fresh air in, and protecting your home's entryway from the elements, but not all of them come cheap. Costco's Genius COOL retractable screen door has gained attention for its simple design that costs a fraction of the price of other doors. With a $199.99 price tag, it's significantly more affordable than the $700 custom storm door that one reviewer had before they purchased this model from Costco. However, that alone doesn't make it the best choice for homeowners. 

Costco's model stands out for being DIY-friendly and quick to install. According to real customer reviews and TikTok videos with thousands of views, most users manage to set up Costco's affordable storm door in about 30 minutes. The screen arrives in just five parts and fits doors between 32 and 36 inches wide. While it's praised for its solid frame and smooth glide when clean, multiple reviewers note that the track must be well maintained — dust or debris can cause the retractable screen to stick or misalign. One reviewer even warned that it adds a 1.5-inch lip to the threshold, which could be a tripping hazard if not accounted for.

Despite a few quirks, many users call the Genius COOL model a reliable choice for back doors or patios where security isn't the top concern. For the price, it competes well with premium models, as long as buyers understand the maintenance needs and install it with care.

While many buyers find Costco's screen door a solid choice, it's not without limitations. Some of the downsides that may make you reconsider installing a storm door are mentioned in buyer reviews, including the need for frequent track maintenance. Compressed air and silicone spray can help prevent the door from sticking, but it's still an inconvenience. For households with pets, especially large dogs, a retractable screen might not be the most durable choice. Several social media users noted that pets ran through the screen before realizing it was closed, potentially damaging it.

As noted in Amazon reviews, for light-use areas where airflow is the concern, the door is a convenient solution. Assembly may need two people, especially when aligning the screen tracks. Some customers have had to modify latch positions by drilling new holes, so a willingness to tinker is necessary if you want to keep bad weather out with extra storm door installation information. Once it's installed, homeowners benefit from smoother operation with a few tweaks and some product care. 

While Costco's retractable door may not be as seamless or maintenance-free as others, it offers enough quality and versatility to meet the needs of most homeowners. And with Costco's generous return policy, hesitant buyers don't need to worry. If your door does break, there are plenty of unexpected ways to repurpose a screen door in your home and garden instead of just throwing it out after the return policy deadline.
