What Customers Are Saying

The underlayment is generally well-received, with customers praising its ability to provide a quiet, level, and comfortable floor. It is described as easy to install, with a fan-fold design that smooths over minor subfloor imperfections. The product is also noted for its sound-dampening and insulating properties, adding warmth and comfort. However, some customers have encountered issues with the interlocking system, finding it difficult to align the pieces. A few reviewers felt the underlayment was too thin and not as comfortable as expected. Additionally, the metalized foil layer was found to block WiFi signals in some cases.

Horrible interlocking system

The interlocking system works only for the first few feet. I end up cutting it off to be able to use this product. I definitely don't recommend it!
