The material is durable, odorless, and non-toxic, making it safe for indoor use. Users will appreciate the stylish hexagonal design which not only helps in reducing noise but also adds an aesthetic touch to any room. Installation is straightforward, although it should be noted that no adhesive is included, so buyers will need to purchase construction adhesive or double-sided tape separately. This could be a minor inconvenience for some.

The panels are versatile and can be cut to fit different spaces without compromising their performance. The thinness of the panels may be a concern for those needing maximum soundproofing. Additionally, while the panels are designed for easy installation, the need to buy additional adhesive could be seen as a hassle.
