The plastic material itself is fairly durable, although the adhesive tape may need annual replacement due to wear from sunlight and normal stress. This kit is easy to install and use, which is a significant advantage for those unfamiliar with DIY projects. However, it must be removed if you wish to open your windows in warmer months, which can be seen as a drawback for some users.

Another downside is the potential need for seasonal reapplication to ensure a proper seal, indicating a bit of maintenance is needed. Aesthetically, its clear plastic design is unobtrusive, blending well with most window styles.

The inclusion of extra wide tape helps in providing a more secure seal, which means less maintenance over time as it reduces the likelihood of the tape peeling off.

However, it is important to note that the product does not offer ultraviolet light protection, which may be a consideration for those concerned with sun exposure and fading interiors.
