Seems pretty good
Apparently didn't have any in stores near me, so it had to be shipped, works well enough. This vent sealing tape doesn't have the fiber reinforcement, but it adheres pretty good, and forms a pretty tight seal. I have no complaints.

Nothing
I use this to seal between insulation I install on HVAC ducting

Picking up Order
Had a bit of a problem picking up order. I did not receive a 'ready for pickup' notification. After 2 days I went to Lowes and they finally found it in one of the lockers. Apparently, the transaction was never closed out. Not a big thing. Just add to your lessons learned to make sure it doesn't happen again.
