**** The Flex Seal Draft and Insulation Sealing Tape appears to have garnered mixed feedback from customers regarding its effectiveness in sealing drafts around windows and doors. Many users agree that the product performs well at keeping cold air out, which ultimately saves energy and money. Reviews highlight the importance of ensuring that surfaces are clean prior to application, as this significantly impacts the tape's adhesion. Several customers noted the need for additional measures to enhance the tape’s sticking ability, particularly on metal surfaces. Some reported using a stronger double-sided tape to secure the Flex Seal tape more effectively. The two-inch width of the tape has been mentioned as a disadvantage, especially for users with larger gaps around doors, as they found it necessary to trim the product carefully to avoid complications when closing doors. While some customers expressed satisfaction with the product, stating it is the first insulation tape that has stayed adhered, others had less favorable experiences, citing issues with the tape peeling off shortly after application. Overall, Flex Seal Tape shows great potential in improving insulation but may requires careful preparation and possibly supplemental adhesive to achieve the best results. **
